I am trying to use the datepicker javascript from nfstools.com/tips/DatePickerTest.htm I have a php function (userform) that controls the output of the form fields and I also have a javascript function (displayDatePicker) that is part of the same php file. The javascript works if I have it separate from the php function like this:

Code: 
<form>
Expiration Date: <input name="date_expired"> 
<input type=button value="select" onclick="displayDatePicker('date_expired', this);">
</form>

But when I try to interlace my php function with it, I can't seem to get the syntax and the quotes correct. This does not work:

Code: 
   echo userform ($lang['Date_Expired'], "<input name='date_expired'><input type=button value='select' onclick='displayDatePicker('date_expired', this);'>");

Any ideas?

My personal saying - Just remember, it can always get worse, and usually will.

You're doing to have to diffentiate strings better in that parameter you pass to the function.

echo userform ($lang['Date_Expired'], '<input name="date_expired"><input type=button value="select" onclick="displayDatePicker('date_expired', this);">');

sleipnir214,

Thanks for the assistance. I also got a response back from the developer. He indicated that I should modify the line as follows:

Code: 
echo userform ($lang['Date_Expired'], '<input name="date_expired"><input type=button value="select" onclick="displayDatePicker(\"date_expired\", this);">');

I don't get an error, but the datepicker does not popup the calendar. I realize this is not a typical php issue, but any help would be appreciated. I have tried alot of different ways to use quotes and separate the strings, but most efforts wind up getting a parse error.

I don't know. I'm unfamiliar with the JavaScript class that this HTML will invoke.

One thing that you should probably do is change:

<input name="date_expired">

for

<input type="text" name="date_expired">


What does your function output? What's printed by the echo statement?

Assuming that this involves the displayDatePicker library published by Julian Robichaux at [ignore][/ignore], and his javascript and example CSS are in the external files test_foo.js and test_foo.css, respectively, then this code:

Code: 
<?php
function test_function ($somestring)
{
        return $somestring;
}

print '<html>
        <head>
                <script src="test_foo.js"></script>
                <link href="test_foo.css" rel="stylesheet" type="text/css">
        </head>
        <body>';
print '
                <form method="post" action="show_post.php">';


$a = <<< EOV
                        <input type="text" name="date_expired"><input type=button value="select" onclick="displayDatePicker('date_expired');">
EOV;

echo test_function($a);


print '<br>
                        <input type="submit">
                </form>
        </body>
</html>';
?>

Works for me.

Don't make yourself crazy trying to get all the internal quotes escaped and double-escaped to output JavaScript code. Use the heredoc syntax to assign the string to a variable then use that variable with your function
