How to make a WooCommerce Product Importer

Okay, I've had to do this for two clients this month, so I thought I'd write a post on how to make a product scraper that works with WooCommerce and WordPress.

2 Ways to Make a Product Importer

Prerequisites:

Before you begin, both method described in this article use the simple HTML Dom library for php which you can download HERE, just download the file and change it from a .txt file to a .php file and include it at the top of your scripts as you'll see below. You may have to copy and paste it into a blank PHP file from the browser window.

The two most common ways to import products from an external source is probably either to scrape the site you want to sell products from or get an Excel or CSV file directly from your product supplier. I have done both methods so will cover the basics here. If you need this done and don't want to do it yourself as it is rather complex, hire me and I'll do it for you at a very reasonable price since I have experience doing it now.

Using an Excel file from the Product Vendor

If you get an excel file from a vendor, you'll need to write an algorithm or application in PHP to convert the Excel file into a CSV file compatible with the CSV importer plugin for WooCommerce seen below:

excel2csv3

So you prob have an Excel file from your supplier that looks something like this:

excelexample

Now to work with the CSV Importer plugin for WooCommerce and WordPress, you need it in CSV format specially formatted to provide specific product information for your shopping cart. The CSV file needs to look something like this one I made for a client recently;

sku;post_name;post_title;post_content;post_excerpt;category;tags;stock;price;featured_image
2156635698;2156635698;3.25 carat round brilliant loose certified diamond;Color: F,Cut: EX,Clarity: SI2,Shape: round brilliant,Loose GIA certified diamond with certification number 2156635698;Color: F,Cut: EX,Clarity: SI2,Shape: round brilliant,Loose GIA certified diamond with certification number 2156635698;loose certified diamonds;GIA certified|colorless|Slightly Included|Peter Michaelson Jewellery;1;61261;http://petermichaelsonjewellery.com.au/diamondsearch/images/roundbig.jpg
2131664334;2131664334;2.35 carat round brilliant loose certified diamond;Color: E,Cut: EX,Clarity: VS1,Shape: round brilliant,Loose GIA certified diamond with certification number 2131664334;Color: E,Cut: EX,Clarity: VS1,Shape: round brilliant,Loose GIA certified diamond with certification number 2131664334;loose certified diamonds;GIA certified|colorless|Very Slightly Included|Peter Michaelson Jewellery;1;63694;http://petermichaelsonjewellery.com.au/diamondsearch/images/roundbig.jpg

Above is what the .csv file looks like opened in a text editor, open it in Excel and it looks a little nicer as you can see below:

csv

So the goal here is to convert the below Excel on the left to the CSV file on the right to use with CSV Importer:

Here is how to convert the Excel file to a CSV file you can upload as a product list into your WordPress WooCommerce website:

Instead of providing a very long explanation about how to make this Excel xlsx to csv file converter, I'm just going to get you started with some code that you can modify to fit your unique situation:

<!DOCTYPE html>

if ($k == 0) continue; // skip first row

</html>

Okay, there you have it! Now on to the next way of getting products into WooCommerce.

Scraping Products from another Website

If you can't get the provider to provide an Excel sheet or product list of some sort, you may have to resort to scraping thier website. Here is a script I wrote to do just that:

First, the HTML:

<h2>Product Scraper for apmex.com</h2>
Created By: Ian L. of <a href="http://jafty.com">Jafty.com</a>

<hr />

<form action="apmex-scraper5.php" method="post">
<table>
<tbody>
<tr>
<td>Page no.:<select id="pgn" name="pgn"><option>1</option><option>2</option><option>3</option><option>4</option><option>5</option></select></td>
</tr>
<tr>
<td>Keyword:

<input id="kwrd" type="text" name="kwrd" value="gold" /></td>
<td>Per/Pg:<select id="per" name="per"><option>60</option><option>5</option><option>10</option><option>20</option><option>30</option><option>40</option><option>50</option></select></td>
</tr>
<tr>
<td></td>
<td><input id="sbt" type="submit" name="sbt" value="Scrape Now" /></td>
</tr>
</tbody>
</table>
</form> 

Then the PHP main page:

//Exports products in given category from example.com into csv file for importing into woocommerce.
$pgno = $_POST['pgn'];//the page no. for get var in the URL to scrape
$keywrd = $_POST['kwrd'];//keyword to scrape search results of scraped site.
$howmany = $_POST['per'];//how many to scrape per page.

//URL String for searching target site:
$u = "http://www.example.com/search?page=1&q=gold";

include 'simple_html_dom.php';

$html = file_get_html($u);//string of HTML for gallery pg
//echo "HTML:".$html;

include 'functions19.php';

//get the short descriptions:
$s = '
<div class="products-item-description">';//'
';
$e = ' get_short_desc($s,$e,$html);</div>
//get the links to product page:
$s = '<h3 class="products-item-title"><a href="';<br />
$e = '">';
get_stuff($s,$e,$html);</a></h3>
//get the price and mark up 15%:
$s = '<h3 class="heading-blue">Volume Pricing</h3>';//'1 - ';
$e = '<div class="products-item clearfix">';//'</div>';
get_prices($s,$e,$html);

//now short-desc, link & price all are in arrays, $d, $l and $p

$icnt = count($l);
echo "Processing $icnt items";
//start the csv file contents variable:
$csv = "post_name,featured_image,post_excerpt,sku,stock,post_title,price,category,post_content,product_gallery,product_id".PHP_EOL;

for($i=0;$i<$icnt;$i++){
$ii = $i+1;

$de = $d[$i];//short desc
$pr = $p[$i];//price
$li = $l[$i];//link
echo "
<h2>Link text we get title from is:</h2>
$li
";
//get the title from the link
$tia = explode("/",$li);//title array will have title at key 5
$ti = $tia[5];
//replace - with space in title:
$ti = str_replace('-',' ',$ti);
//capitalize title:
$ti = strtoupper($ti);
echo "Title: $ti
";

//build cats var for csv file:
//now get the html for breadcrumb/categories:
$html3arr = explode('

<nav class="breadcrumbs">',$html);//key 1 wil have breadcrumbs/cats
$bcchunk = $html3arr[1];//has cats plus, so cut off at</nav>$bccarr = explode('

$catarr = explode('<a href=""/category/',$html3);//key"> //count cat array:
$ccount = count($catarr);
$countmin = $ccount-1;
$cats="";//variable to hold categories(resets it too)
$capkey = ucwords($keywrd);//captialize first letter of ea. word in keyword
$cats .= $capkey;//adds keyword as first category.</a>

for($k=1;$k<$ccount;$k++){
$catcode = $catarr[$k];//has txt b4 and after cat.
$catcodearr = explode('">',$catcode);//key 1 will have cat followed by extra txt
$catplus = $catcodearr[1];//has cat plus txt after.
$catplusarr = explode('',$catplus);//key 0 is just cat!
$cat = $catplusarr[0];//echo "

cat found: $cat

";
$cat = trim($cat);//trim cat
//see if cat is equal to keyword in all its captialized forms
if($cat == $capkey) {
//if it matches don't add it, so do nothing!
}else{//else its not the keyword that was added first, so add it:
//add a pipe at start since its not first one
$cats .= '|';
$cats .= $cat;
}//end if/else cat is same as keyword in a case insensitive comparison
}//end for loop going over cats.

//get the product description for main content:
$darr = explode('

',$html2);//key 1 will have description plus some
$desplus = $darr[1];//desc plus txt b4 and after

$desarr = explode('

if(strpos($desandb4,'

$desc=$desandb4;
}else{
$descr = explode('

$desc = $descr[1];
}//end if/else desc has part we don't want at start

//strip HTML tags from desc:

fclose($fh);
//provide a link to the file to download it:

Important Note:

If you copy and paste code from almost any WordPress blog, including this one, WordPress normally changes single and double quotes(" and ') to fancy ones. You can easily do a find & replace in any text editor to change them back, but if you do not, the script will not function as expected or may not work at all.

cURL & PHP

Scraping with Curl using Cookies

Okay, I got a much needed lesson in scaping today using curl and cookies. I quickly discovered that you can not get the contents of some webpages without using cookies because some pages use cookies to validate requests for pages or other data.

My mission was to scrape the following URL from expireddomains.com:

http://member.expireddomains.net/domains/expiredcom/?start=0&o=changes&r=d

If you knew anything about expireddomains.com, you might know that the URL above is for members only, so the goal of this exercise is to make the web server at expireddomains.com think that you are a logged in user. Here is how:

So, first I tried this:

$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
$html = curl_exec($ch);
curl_close($ch);

echo "HTML:<br>$html<hr>";

That returned nothing but a redirect to the login page of expireddomains.com. So then I read online how to use curl while sending a cookie with the page request and found that this worked:

$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
// cookies to be sent
curl_setopt($ch, CURLOPT_COOKIE, "PUT_COOKIE_HERE");
$html = curl_exec($ch);
curl_close($ch);

echo "HTML:<br>$html<hr>";

That worked! so I was home free, but more importantly here are the steps I took to get the value to replace PUT_COOKIE_HERE:

  1. First, I signed up for a free membership at expireddomains.com.
  2. Then I went to the page I wanted to scrape and made a note of the exact URL which was:  http://member.expireddomains.net/domains/expiredcom/?start=8550&o=changes&r=d
  3. So I copied the URL to my clipboard from step two above and pasted it into the Firefox address bar. Don't hit Enter yet.
  4. Then I opened Firebug and allowed the URL to resolve while Firebug was open so I could monitor the HTML headers sent.
  5. Look for a header that reads: "Cookie" and copy the value and paste it in place of PUT_COOKIE_HERE in the code above. Make sure the value is in parentheses.
  6. Now run your code again and you'll get results as long as that's all the webpage is looking for. I have had some that want a referrer set as well which you can also do with curl. Hint, Google curl set referrer for more information.

Errors with file_get_contents PHP Function

If you get an error on your server that says something like:

http:// wrapper is disabled in the server configuration by allow_url_fopen=0

or otherwise cannot get the PHP file_get_contents function to work, this tutorial is for you.

Solutions

There are a couple best solutions and here they are:

  1. Set your php.ini settings for your server for allow_url_fopen to 1 or true whichever is the case.
  2. use Curl instead.

which solution you use depends on your situation. If you have access to your servers config via the shell prompt or Cpanel, then you should first use number one above. If you don't have such access and your on a shared server that doesn't allow file_get_contents or similar functions, then you have to replace the functions in the app or webpage that is throwing the error. Here is a typical replacement for file_get_contents  using curl:

$html = file_get_contents('http://www.cnn.com');

echo $html;

$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, ‘http://www.cnn.com’);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
$html= curl_exec($ch);
curl_close($ch);

// display file
echo $html;

Simple if you are a PHP developer and workable if you are not I guess. Good luck!

 

 

Google PageRank

What is Google PageRank

PageRank(AKA PR) is one of the methods Google uses to determine a page's importance and therefore it's position in search engine results and the domain name's value in part. The PR of all web pages changes every month when Google does their re-indexing.

How is PageRank determined by Google?
PageRank is determined solely by incoming Links. So to increase your PageRank, increase the number of links to your site. The quality of links is also a big factor in your site's PR. For example, links coming into your site from a site with a PR of 1 are not as valuable as links coming to your site with a PR of 6. Keep this in mind when going after incoming links to your site and check the PR of the sites where you place links.

Is it better to have a high or a low PageRank?
I used to wonder whether it was better to have a zero or a five. Well now that I understand a little about how it works, it's definitely better to have a higher PR than a lower one.
