I'm trying to get the variable to echo in the video embed script below. There are no errors or anything on the page but the page is completely blank when I load it. And when I look at the source code data has nothing in it.

video embed script:
<?php
$dlink = $_POST["decallink"];
?>

<object
type="video/avi"
data="<?php echo $dlink; ?>"
width="100%"
height="100%"
<param name="video" value="<?php echo $dlink; ?>">
</object>

the form:
<form name="decallink" action="/projects/decal.php" method="post">
<input type="text" name="decal" value="Decal Link" />
<input type="submit" value="Submit" />
</form>

Should be
$dlink = $_POST["decal"];
to get the submitted value.

$dlink = $_POST["decal"];
to get the submitted value.

? tried it and it didn't work. also [""] is the form name, which is decallink, not decal.

That's probably the extra slash in front of this

action="/projects/decal.php"

but you'll still need to make the change I suggested. I tried it and it worked.

so you should check your script url '/projects/decal.php'
if you process data in the same file, try to remove action="/projects/decal.php" from form tag and run script

Actually, $_POST['whatever'] references a passed variable... a form does not pass a variable, elements in the form do. In this case, 'decal', which is your input. The name of the form is irrelevant and not passed.

Also, NEVER use REQUEST. REQUEST guesses from two sets of variables... you should know if you're getting a POST or GET, never let the system decide for you.

Finally, can you post your updated code? We can't really guess what where you're going wrong.

after changing the coding around, I changed it back to the original. So, its the same as my first post right now.

EDIT: Changed $dlink = $_POST["decallink"] ; back to $dlink = $_POST["decal"] ; again and its giving me a 404 error. I'm guessing the script is thinking the link is on my site, which is why is 404'ing

Wait,

so "/projects/decal.php" is not on your site? You would need to put the full address like so: http://sitename.com/projects/decal.php

Also, changing what variable you pull should not give you a 404... it shouldn't be changing your URL at all...

Delete your object and echo out $dlink on its own, tell us what happens.

no, /projects/decal.php IS on my site. I'm talking about the link I'm entering into /projects/dce.php (the form)

works perfectly. But with the object it gives me a 404.:confused:

works perfectly. But with the object it gives me a 404.:confused:There's an error in you markup for object. After height="100%" there should be a >.

Keleth

Then the object is failing... has nothing to do with your PHP anymore, if the url is coming out right, its working. Check the link you're connecting to, and make sure that's right.

There's an error in you markup for object. After height="100%" there should be a >.

added the > in but still gives 404 error... ugh starting to get a headache from this. gonna take a break...

EDIT: OMG... wow... fixed it. the problem was that I had to use http:// when I entered the link into my form... well that and the $_POST["decal"]; ... well thanks for all your help guys and sorry for wasting your time...
