PHP and Javascript

iandobrien

Just wondering if someone might be able to help with this problem, I have some Javascript code that opens a window in my browser (using window.open etc.) I then write in what i want to appear in the window using 'document.write'. The problem arises when i want to input a PHP variable into the window. I have a little text box that contains (well is supposed to) the PHP variable. I do this with the following code...

<input type ="text" name="first" value="<?php $first ?>" align="top">

The problem is that the Javascript doesn't recognise the PHP and either an error occurs on the page or nothing is printed out in the text box!!Its something to do with how i'm setting the value (value="<?php $first ?>"). Is there a way around this??I tried declaring a javascript variable and letting it equal $first
(ie. var This_Var = "<?php $first ?>"😉
and then letting the value equal this variable (ie. value ="This_Var")
but this again didn't work...anyway, does anyone have any suggestions as to how to get around this, thanks,
Ian

You cannot execute php code in the browser.

no, i can execute the code but i now realise what the problem is..the reason it wouldn't print out the name was because my name is 'Ian O'Brien' and the ' between the O and the Brien was what was causing the problem...so if i just entered Ian as the name that was going to be used in the text box then the code would work fine...any way around this????Thanks

what i'm trying to get at here is that if you have a sentence that you are trying to print to your screen using javascript, how can you make sure the sentence prints out even if it contains an aposthrophe??For instance someone might enter a sentence and we're not sure whether that sentence will contain any apostrophes but what we want is to make sure the sentence prints out as it was written in (even if it contains apostrophes!)thanks,
Ian

not sure, but you probably want to look into one of three functions:

htmlentities
addslashes
urlencode

or some combination of them.
