I looked around the forum but couldn't find this answer but sure it has been solved before....

Is there any sample code to validate a numeric form value.

For instance, I want the user to type in a number in the form and make sure the value is between 1 and 50.

Any suggestions?

Hi mruetz,

Yes, I think I posted this yesterday (but my memory could be failing).

I have been looking for it but haven't found it yet (using search and browsing as well). I will continue to look for it, but if anyone finds this thread, please post a link. Many thanks, Matt

Hi mruetz,

Well I can't find it either - I'll try again in the morning (or re-write it).

Bob

Thanks Bob!

Try to make an advanced search and set the author to greyhead and look for his posts at 22,21,20 of this month ?

Hi mruetz,

Something like this added to your Form HTML (not the Javascript box)

<?php
$script = "
var field_id = new LiveValidation('field_id');
field_id.add( Validate.Length, { 
  minimum: 4, 
  maximum: 8 
});
";
$script = "
window.addEvent('domready', function() {
  $script
});
";
$doc =& JFactory::getDocument();
$doc->addScriptDeclaration($script);
?>

Note : only the two script lines var field_id . . . and field_id.add do the validation. the rest is to load it correctly into the page.

Replace 'field_id' three times with the id of the field you want to validate; and set the max & min parameters.

Hi Bob,

How can I ensure a minimum value of 10.00 in a field.

Found it:

<?php
$script = "
var text_0 = new LiveValidation('text_0');
text_0.add( Validate.Numericality, { 
  minimum: 10
});
";
$script = "
window.addEvent('domready', function() {
  $script
});
";
$doc =& JFactory::getDocument();
$doc->addScriptDeclaration($script);
?>

Thanks!
