Skipping code

I have this code that is part of a larger php file which I am struggling with.
I am trying to pass in a variable from php 'aoa' which is a date, but when the program runs to the first line of javascript code, it does not process the variable being passed in and just jumps out of the script and continues on with the php. Any suggestions?
PHP Code:
textbox_list("Name","input","project_desc",$row['project_desc'],45,$tab++).
'<li><label for="aoa">AOA:</label>';
?>
<script>
var check_date='<?php echo $row['aoa']; ?>';
document.write(check_date)
if (!check_date){
DateInput('ship_date')
}
else{
DateInput('ship_date', false, 'YYYY-MM-DD',check_date)
}
</script>
<?php
echo '</li>'.

Javascript only runs once the page is served to the client browser and php scripting is over and done by then.

Exactly.
You can use php to write Javascript but I don't think you need to in this case - just remove the document.write line and access the variable by its DOM reference. Read the tutorials on http://www.w3schools.com/htmldom/default.asp if you want good basic info. |

Guys, thanks for the replies. I understand what you mean about it php is over and done with but still cannot figure this out.
This is the link to the source code for the calendar that I am trying to incorporate into the site.
http://www.dynamicdrive.com/dynamici...oncalendar.htm
To your point Chirshirst, I tried to modify the code by removing the if statement to be part of the php so that is decides which bit of javascript should be used.
I also thought as you pointed out about javascript running on the client side that I should then try to echo the statement so that it get interpreted by the brouser, but that did not lead me to any further success.
I have attached all the code below as well for reference.
Bit more help please.
PHP Code:
if(empty($row['aoa'])) {
?>
<script>
var check_date='<?php echo $row['aoa']; ?>';
DateInput('aoa')
</script>
<?php
}
else{
?>
<script>
var check_date='<?php echo $row['aoa']; ?>';
DateInput('aoa', false, 'YYYY-MM-DD','<?php echo $row['aoa']; ?>')
</script>
<?php
}
PHP Code:
<?php
// start session
session_start();
// set up some global variables
@include 'menu.php';
echo '<link rel="stylesheet" type="text/css" href="style/form_style.css" />';
if(isset($_POST['project'])){
$field_list=array( 'work_flow', 'network_number', 'documentum', 'pdit',

'submit_office', 'document_level', 'margin_level', 'contigency',
'financials', 'owner', 'customer', 'consultant',

foreach ($_POST as &$field){
$field=sanitizeMySQL($field);
}
if(!empty($_POST['consultant']))$_POST['consultant']=lookup("tbl_company",$_POST['consultant'],"company","company_id");
if(!empty($_POST['customer'])) $_POST['customer']=lookup("tbl_company",$_POST['customer'],"company","company_id");
if(!empty($_POST['owner'])) $_POST['owner']=lookup("tbl_company",$_POST['owner'],"company","company_id");
}
//Update Project details
if(!empty($_POST['project_id'])){
update("tbl_project",$field_list,$_SESSION['project_id']);
echo '<head>'.

Depending on whether the variable $row['aoa'] is null or not it needs to change the way it calls the function DateInput.

And what does or does not happen?
Because we can't recreate any of this without your database.

I have checked that the value $row['aoa'] is correctly registering the value that it should. When I try to run the code, I currently getting the following error message
Quote:
|
Parse error: syntax error, unexpected T_STRING, expecting ',' or ';' in D:\Documents and Settings\414004425\My Documents\pet\display_project_details.php on line 64
|
Line 64 is the var check_date line
PHP Code:
if(empty($row['aoa'])) {
echo'<script>'.
'var check_date=<?php echo $row['aoa']; ?>'.
'DateInput('check_date')'.
'</script>';
}

'var check_date=<?php echo $row['aoa']; ?>'.
should be = $row['aoa'] ie remove the echoing! Sort out the quotes and check your IF condition - should that be !empty ?

What about just changing the whole bit to..
$blaa = $row['aoa'];
if(empty($row['aoa'])) {
echo '<script>
var check_date='.$blaa.'
DateInput(\'check_date\')
</script>';
}

In response to PaulW, don't you need to have the $row['aoa'] as a php variable that needs to be passed into the script hense the need for the <?php...?>?

No. What you're doing is building up a string - the fact that it's Javascript is irrelevant - you're not "passing values" to anything. It's the same as $str = "the value = " . $row['aoa'] . " some more text";

That is; that code snippet should be
PHP Code:
if(empty($row['aoa'])) {
echo "<script>"
. "var check_date=" . $row['aoa'] . ";"
. "DateInput('check_date');"
. "</script>";
}
Although, as Paul pointed out. You probably don't want to use the row data if it's empty. So maybe the check_date variable should get another value?
