Form not responding correctly.

[timmah1]

Hi,

 

I have this form that checks the PR of domain names entered into a form.

It works great, except that no matter how many names you search for, it only shows the first domain entered.

 

I'm sure it's something incredibly simple, but I've been staring at this code for the past 2 days and can't figure it out.

This don't require a database, so you could implement it on your site to test.

 

Please help me!

Thanks in advance for any help.

It's because $tempurls only contains a single URL.  You aren't looping that at all, and I think parse_url will only return a 'single' URL.  Trying using print_r($tempurls) and I think I'll be right.

 

What is $_POST['urls'] variable supposed to contain?

[timmah1]

$_POST['urls'] are from the textarea

[timmah1]

I'm confused on exactly where to put print_r($tempurls)

[nloding]

print_r won't fix it.  But put it right after you create the $temprurls variable -- it will print out the array.  And I think you'll see it's not an array, but a single value, which is why it's only showing that one value.  You need to explode $_POST['urls'] first, then do a foreach statement, and then process the URLs.

 

<?php
$exploded_urls = explode("\n", $_POST['urls']);

foreach($exploded_urls as $key=>$value) {
// Do your processing here
}
?>

Thanks nloding.

 

Still don't work though. I have no idea how to fix this

[nloding]

I think you next need to look at your functions.  What the heck are they doing?  The answer is nothing.  Those function's are just being defined -- I don't see them being called anywhere.

[timmah1]

I wish I knew the answer to that, like I said, it's not my code.

Some college student did this site for his 'project', now they want things moved around, and I'm at a lose

 

 

[nloding]

No, no.  I gave you the answer to my rhetorical question.  The answer is literally nothing.  The functions are being defined, not called.  Not to sound mean (if I do, it's because I'm running few hours of sleep) but if you don't understand the difference between calling and defining functions, please go to the book store and pick up a beginning PHP book and start again.

 

What you need to do is cut and paste those functions above the rest of the code.  Then replace where they were with calls to them.  I do not know what variables to pass to them.  You gotta figure that part out.
