$php_self, firefox, opera and exlorer problem

[emrys404]

Okay, i devloped my site in firebird/fox and now i'm trying to get some cross browser compatibility going, mainly with explorer and opera at the moment. Among other things, my main problem is that explorer and Opera cant seem to process this line of php code

<form method="post" action="<?php $PHP_SELF ?>">

a quick look at the source from these browsers reveals:
<form method="post" action="">
All 3 browsers show this, but explorer and opera wont execute correctly
Firefox works great and processes it fine. Any suggestions?
thanks in advance

try echo....
<form method="post" action="<?php echo $PHP_SELF; ?>">

Also, instead of $PHP_SELF, use $_SERVER['PHP_SELF'] 😉

OKay i tried: <form method="post" action="<?php echo $PHP_SELF; ?>"> before as well, but it didnt work either. Is it supposed to?
I"ll give $_SERVER['PHP_SELF'] a try, but whats the difference?

Thanks

Your setup might have register_globals set to off in your php.ini which will cause $PHP_SELF to not work, instead you need to use $_SERVER['PHP_SELF']

The difference is [man]register_globals[/man]. Only with register_globals on will $PHP_SELF work. On or off, $_SERVER['PHP_SELF'] would work.

OKay i found the problem. It was not with the $PHP_SELF but with the submit button itself:
<input type="image" src="images/submitbutton.jpg" name="submit" value="Submit">

I know this because when i replace the image button with a standard button ie. <input type="submit"> it works fine on all browsers. Again it works in Firefox/bird but not in Opera nor Explorer. Any ideas? Also i should mention that the tests are conducted via apache running on my local machine so the conditions are about as similar as you can get.

Thanks in advance,

Anyone have any ideas? this problem is driving me crazy.

it works in firefox because that browser will post or get the page to itself by default if there is nothing specified in the form's action.

as for it working when you use IE or opera, I can't say. I created a form with an image for the input and it worked fine for me in IE.

post the code for the form, maybe something else is causing the problem.

Okay i recreated the error using these lines:

<?php

if($_POST['submit'] == "Submit")
{
	echo "It worked!";
}

else
{
?>
	<form method="post" action="<?php $PHP_SELF ?>">
	I am:<input type="text" name="name" size="20" value=""> 
	<br>
	<center>
	<input type="image" src="images/submitbutton.jpg" name="submit" value="Submit">
	</center>
	</form>		

<?php
}
?>

Again this works beautifully in Firefox, but not in Opera 6 or IE 6.
Also again i am conducting these tests on my local machine running apache, but i have uploaded it and tried it on a different machine with the same result.
The specific problem with it is when hitting the submit button it merely reloads the page (which was why i initially thought it was with the $php_self)
Hope that clarifies a few things
Thanks in advance

Are you just hitting enter while focus is in the text input, or are you always using your mouse to click the submit button? In IE it won't send the submit button's info if you just hit enter in a input field if I'm not mistaken.

[emrys404]

I just tried it and hitting enter and clicking on it give the same result.

Thanks

Can someone please try and run the code and tell me what they get?
Is there a function to see any and all data being submitted via post? but that wouldnt make much sense because even isset() doesnt work (i guess that means its not even making it to the $_POST variable).
I took out the $php_self just to be sure and the form action works fine, it calls the new page, but the submit data doesnt go through. It does open an email when i change the action to a mailto:, however.
I cant for the life of me see whats wrong with it and its driving me nuts. I've checked a number of online tutorials for reference, but they all say the same thing. Any thoughts, suggestions, ideas?
Thanks in advance,

I've simply used: <input type="image" src="button_submit.gif" border="0"> (minus the name and value) and it works fine.

You posted this again:

<form method="post" action="<?php $PHP_SELF ?>">

And my concern is this:

<?php $PHP_SELF ?>

This tells PHP to do nothing. Period.

You need <?=$PHP_SELF?> or <? echo $PHP_SELF?>. If using those you still see the action attribute blank, then you'll probably need to use $_SERVER['PHP_SELF'].

Give that a whirl and see what you get. Check the source code and copy the HTML output of the form action if its still not working.

I would have to say, I did try out the code you posted and I can not get it to work in IE. I would say the only thing is that IE doesn't support or use the tag <input type="image"... in the same manner as Firebird. Cause if you change it to a submit button everything works fine. I could be wrong, but that is all I could come up with. I even tried Astrotag's method, which I can't see how that would work, but it didn't work either. Sorry.

[csousley]

I would change your post method to get and just see what's really being passed.

[tshafer]

You could try

if ( isset($_POST['submit_x']) ) {
        ## ...
}

if it's an image button (<input type="image" ... />)

[AstroTeg]

First make sure the action="" has a value. If its blank, then you've got a problem.

Second, make sure the page submits and the script can get the values.

<input type="image" src="image.jpg"> is a very standard HTML tag. If IE isn't handling it, then you have a problem somewhere else (the beauty in IE is the problem isn't always where you expect it to be).

As tshafer mentioned, the problem may be with your PHP code that checks if the form was submitted.

rgermain>> Thanks for testing it out, at least now i know i'm not cursed 🙂

AstroTeg>> At first i though that the $PHP_SELF was the culprit, and i ended up checking out all variations of php_self and found that ie worked with them all even though the source said action="". i did get action to show something by using echo $_SERVER['PHP_SELF'] , but it doesnt seem to make a difference.

I tried changing the method to get. and this is what is happening:
in firefox:
/temp.php?iam=blah&submit.x=70&submit.y=16&submit=Submit
and in ie:
/temp.php?iam=blah&submit.x=70&submit.y=16

as we can see IE is not assigning a name and value to the submit button.
So now that we know the problem is there anyway to fix this?

Thanks for all your help

Toss a hidden variable in there called submit and set the value to submit.
