How To Create A http Get Request URL?

Posted on 2014-01-09

Last Modified: 2014-01-09
I am using a MYSQL Server and using php to run an Inventory Search page on my website.
A supplier of ours is requesting us to provide them with a HTTP Get Request URL that implements a part search on our website. Currently I use a form on our website that searches a database table for the item and displays the results on an inventory_srch_results page.
Is there a way of doing what our supplier is asking?

Our website is: http://www.escomponents.com (The home page has a search form)
The results page is: inventory_srch_resultsRR.php

Any help would be greatly appreciated.

Thank you...
Rick

Data can be transmitted to a web server either via POST or a GET. When you POST data to a web server from a search form, for example, the data doesn't show up in the address bar.

Your search results still looks like this:
http://www.escomponents.com/inventory_srch_resultsRR.php

A GET request is when you are just asking the web server for a specific page, but you're not POSTing data. So when you go to your home page in your browser:

http://www.escomponents.com

...that is a GET request.

You can also pass data in a GET request, in a part of the URL known as the "query string." If you see a question mark in a URL, you're seeing the part that splits the URL from the data.

So if I went here:

http://www.escomponents.com?hello=world&name=Rick

...then I am still getting the same page, but PHP has access to GET variables called "hello" and "name". The value for the "hello" GET variable is "world", and the value for "name" is "Rick".

Now, currently your search form sends POST data to the inventory search engine, and your search engine expects POST data. For example, the field that it sends for the search word is called "srchCriteria".

Your supplier seems to be asking you for a version of your inventory search engine that will allow them to type in a part number in the URL and search that way, like this:

http://www.escomponents.com/inventory_srch_resultsRR.php?srchCriteria=ADG

However, it seems that your search engine is only looking for POST data and not GET data.

One quick way of resolving this (but not necessarily the best way) is to change any references to $_POST in the search engine results page to $_REQUEST. The $_REQUEST variables look at both POST and GET data and takes whichever one is available.

All that said, I would be cautious about doing this and would suggest hiring a freelance developer (elance.com and sites like it have contractors for hire) to make the change. You could accidentally open up security risks if you are not careful with what you're changing or understand all of the changes.

Also, just for additional information...

Usually when third parties want to search your site for information using GET data, they are often building their own tools to programmatically access your data. They probably have their own system and they want that system to automatically do searches as necessary without people actually having to go to your web site.

The concept called "REST" services is usually what they are looking for. REST is basically a fancy acronym for someone giving you their search parameters via GET, and you returning some kind of formatted response. Often times, people don't want a full web page with all the images and all that, but an encoded response that is easy for programming languages to read. A lot of REST services return data in JSON-encoded format. This simply means that instead of sending back a bunch of HTML with all the images, headers, footers, etc... you're sending back a response that looks like:

[{ "ADG123" : { "Supplier" : "Me", "Colors" : ["Green","Blue"] }, "ADG456" : { "Supplier" : "MeToo", "Colors" : ["Red"] }];

It's not very easy to read by humans, but it's really easy for programming languages to read.

So that might be something you want to ask your supplier ("Do you want the GET version to return JSON-encoded data?") ....if you're going to provide this functionality for them. Not only will it make them happier, but it will reduce the amount of data that you have to send them each time.

I did make the change to $_REQUEST on the inventory_srch-resultsRR.php page.
When I enter a search
http://www.escomponents.com/inventory_srch_resultsRR.php?srchCriteria=2n2222a

all I get for results are all of my products. I should only get approx. twenty items.

Is there something else that I need to do?

Thank you again for your quick response and I do understand what you are talking about.

It probably means there's some other code that isn't being executed properly. If you want to post the code for the search results page, we might be able to figure out what to change.
