How to embed javascript in php code

scoobie · January 23rd, 2005, 06:42 AM

Hi,

i was wondering if anyone can help. i am trying to get a simple alert msg box to appear when a user types something wrong: i have tried the following code:

if (!$FNameFrm)
{
echo "<script type = "text/javascript">\n";
echo "alert('You must enter first name');\n";
echo "</script>";
exit;
}

if this cant be done can anyone tell me how i get this msg to display on same page instead of oprn another page with just this message on it.

echo "You have not entered all details.<br>Please go back and try again.";

Thanks in advanced

This:

if (!$FNameFrm)
{
echo "<script type = "text/javascript">\n";
echo "alert('You must enter first name');\n";
echo "</script>";
exit;
}

Should be:

if (!$FNameFrm)
{
echo "<script type='text/javascript'>\n";
echo "alert('You must enter first name');\n";
echo "</script>";
exit;
}

Note the change of quotes.

hth,

i have another problem. the alert box comes up but when i click ok it gives me a blank white screen. how do i get it to return to the page so they can re-enter their name when they click ok on alert box.

Hi, i'm kinda new to php. how would i embed my adsense javascript code which looks like this:

<script type="text/javascript"></script>
<script type="text/javascript"
src="http://pagead2.googlesyndication.com/pagead/show_ads.js">
</script>

into a php file. I have a script that essentially shows a sitemap of my site.

For reference, it can be seen at:

jilly,
Add this script in to one page call ads.php, and call this to your main page like
<?php
include("ads.php");
?>

Hi,
Sorry I forot to attached the code in my previous post.
Thank you
Amrita.

<head>
    <title>Untitled</title>

<script language="JavaScript">

function point_it(event){

    pos_x = event.offsetX?(event.offsetX):event.pageX-document.getElementById("pointer_div").offsetLeft;

    pos_y = event.offsetY?(event.offsetY):event.pageY-document.getElementById("pointer_div").offsetTop;

    document.getElementById("cross").style.left = (pos_x-1) ;

    document.getElementById("cross").style.top = (pos_y-15) ;

    document.getElementById("cross").style.visibility = "visible" ;

    document.pointform.form_x.value = pos_x;

    document.pointform.form_y.value = pos_y;

}

</script>
</head>

<?if(1==1){?>

                 <legend>Image View</legend>

<form name="pointform" method="post">

<div id="pointer_div" onclick="point_it(event)" style = "background-image:url('vImage.jpg');width:500px;height:333px;" >

<img src=<img src="images/n.jpg" id="cross" style="position:relative;visibility:hidden;z-index:2;"></div>

You pointed on x = <input type="text" name="form_x" size="4" /> - y = <input type="text" name="form_y" size="4" />

</form>

             <?=$folder.$vThumbImage;?>

this:
if(1==1){

must be closed with a bracket }
somewhere
or don't use this <?if(1==1){?> at all

and :
<img src=<img src="images/n.jpg" id="cross"

must be
<img src="images/n.jpg" id="cross"

i think
