Javascript and PHP

empire

Hi, i have made a shopping cart where images swap onMouseOver...it worked before i turned the html page into a php page. i was wondering if javascript works on a php page?
one potential problem that i see might be that where i define the functions are out of the echo " and the images where onmouseover is, is inside the echo" . does that matter? i can post the code if you need. thanks

another problem that i might have is: because you are supposed to use ' instead of " inside the echo" . well what if i already had the ' in the code (where the 'blah' is in the following code)? does it change to something else? example: normally i'd use onMouseOver="MM_swapImage('blah')"
with echo i have to do: onMouseOver='MM_swapImage('blah')'

You can use the " inside an echo... Just escape it with the backslash...
Something like:

echo "\"this echoes this message with quotes\"";

Cya

And you can have your js function outside php and use the onMouseover inside the echo... I dunno much about js but it works

empire

so did what i say make sense? i cant use 2 pairs of ' inside of each other. should i use /" and then a ' ?

Xo_

Well, but be honest, I think you can use 2 pairs of '.
But I also think that u can lose some of those when echoing some javascript code...
Nothing like try it man 😉...

Cheers

Try something like:

<td><a href=\"items.php?CA=1&UID=$UID onMouseOut=MM_swapImgRestore() onMouseOver=MM_swapImage('tshirts','','../images/tshirts2.gif',1)\"><img name=tshirts border=0 src=\"../images/tshirts1.gif\" width=250 height=25></a></td>

If that doesn't work, I cannot help you... I'm kinda new here too 🙂

You certainly don't need to put the entire row in the echo statement; it would be less confusing all round (and faster running) as

      <tr> 
        <td height="355" align="center" valign="middle"> 
          <table width="65%" border="0">
            <tr> 
              <td><img src="../images/mensclothing.gif" width="250' height="25"></td>
            </tr>
               <tr> 
              <td><a href="items.php?CA=1&UID=<?php echo $UID?>" onMouseOut="MM_swapImgRestore()" onMouseOver="MM_swapImage('tshirts','','../images/tshirts2.gif',1)"><img name='tshirts' border="0" src="../images/tshirts1.gif" width="250" height="25"></a></td>
            </tr>
          </table>
        </td>

That said, PHP does have a third method of quoting strings that uses neither ' nor " but a string chosen by the programmer instead. But again, just echoing the bits that need to be echoed is faster.
