I have a php/mysql script that returns a series of records to populate a form. The number of records returned varies from 1 to as many as 100. On the display page, each record has a checkbox to indicate that the record is being edited. This is checked on the results page to know which records to update. The checkbox code is:
<input type=\"checkbox\" name=\"ed[{$row['id']}]\" value=\"Y\">
This part of the system has been working perfectly for weeks.
Now I've been asked to add client side validation to make sure at least one of the records (checkboxes) has been checked before sending the data to the results page. (The results page already has working validation code in it.)
I've have the following javascript code that should work for my purposes if I can figure out how to dynamically build the javascript code.
<SCRIPT> function validate() { if (!(mainform.ed[0].checked || mainform.ed[1].checked)) { alert('Please check at least one record before submitting this form.'); event.returnValue=false; } } </SCRIPT>
This is the line I need to build dynamically:
if (!(mainform.ed[0].checked || mainform.ed[1].checked)) {
It can't be done that way because the brackets have a different meaning in Javascript syntax. You need to quote the whole name.
You may want to take a look at the example that comes with this forms generation and validation class that supports the exact same type of validation that you want:
