crazy problem of "&"

[diamondnular]

Hi all,

 

I am trying to write a php code which will output a javascript like this:

	$text = "
<script type=\"text/javascript\">
var FO = "a&b";
        ....
</script>
";
return $text;

 

but when I check the output html code, it becomes:

 

<script type="text/javascript">
var FO = "a&b";
        ....
</script>

 

It seems that "&" has been changed to "&". How can I prevent this? How can I output just "&" in html code?

 

Thanks,

 

KC

i believe php has a built in function that converts it for you (in the php.ini), but what's more likely is your web browser is doing it for you when you view html. FF corrects common html errors that is sees in the code.

Hi Neoform,

 

Thanks. If the browser does that job, so how can I rewrite the code so that in the html source code, it should be "a&b" not "a&b"? Javascript does not recognize "&" though.

If you are using firefox it would be a setting particular to firefox. I would check it with IE by viewing the source.

 

I really do not like that aspect of firefox although it can be handy sometimes.

 

What browser are you using to view the source?

Hi,

 

I just used IE to check the code, and even source code is "a&b", IE still reads the code just fine, and the code works in IE. But it seems that FF does not read the code as "a&b" then javascript does not work! It is so strange! Anybody has idea to overcome this problem?

 

Bests,

 

KC.

Maybe that will help?

why dont you just type and in instead?

You have some unescaped double quotes in your original sample. Try something like this:

<?php
$text = '
<script type="text/javascript">
var FO = "a&b";
        ....
</script>
';
return $text;
?>

Yes Ken, I had some typo when typing the question. But inside my real code, it was written correctlY:

 

$text = "
<script type=\"text/javascript\">
var FO = \"a&b\";
        ....
</script>
";
return $text;

Ken meant to replace your double quotes with single quotes.

It might work - as it seems like PHP is somehow replacing '&' with the HTML entity.

I finally came up with solution by using javascript unescape function, then I can avoid annoying "&":

 

$text = "
<script type=\"text/javascript\">
var FO = \"a\" + unescape('%26') + \"b\";
        ....
</script>
";
return $text;

 

Thanks everyone.

Hi Poirot, I understood what Ken meant anyway, because before posing question here, my original code was wrapped with single quote and it did not work, as "&" is always change to "&" no matter what kind of quote you use.
