Hi All,

Kindly need your help, perhaps some of you can give me a clue why when I create table for a form in choronoforms I've got error when the type of field in table set to DATETIME or DATE type. Below are error code :

Fatal error: Call to a member function getError() on a non-object in C:\AppServ\www\instrument\administrator\components\com_chronoforms\admin.chronoforms.php on line 534

Thanks in advance for any response.

Regards,
Zul

Hi Zul,

There's a bug in the Admin Table Saving code. Line 534 is JError::raiseWarning(100, $row->getError()); but $row is not defined, it needs to be JError::raiseWarning(100, $database->getError());

Thhis bug only shows up when there is an error in the underlying MySQL query - if you fix it you should get a more useful error message.

Hi Bob,

Thanks for your reply. I have solve the problem, when we create a table from chronoforms control panel the default type of field is "VARCHAR" and size "255" when I change the type to "DATETIME" I have to delete the size (left the size empty) and everythings goes right.

Bob, Can I have your advise for my below problem? I wan to create cascading select box in my form and I have try your tutorial before but I am not success yet to create cascading dropdown select box. Below is my select box, kindly request your advise :

<div class="ccms_form_element cfdiv_select" id="category_container_div"><label for="category">Category</label><select size="1" id="category" class=" validate['required']" title="Category" type="select" name="Category">
<option value="">Please select a Category</option>
<option value="FGS-System">Fire, Gas and Safety System</option>
<option value="PPS-System">Process Plant Safety System</option>
</select>
<div class="small-message">Please select a cetegory</div><div class="clear"></div><div id="error-message-Category"></div></div><div class="ccms_form_element cfdiv_select" id="section_container_div"><label for="section">Section</label><select size="1" id="section" class=" validate['required']" title="section" type="select" name="section">
<optgroup label="Fire, Gas and Safety System" id="ss_1">
<option value="">Please select a section</option>
<option value="Fixed Fire Fighting System">Fixed Fire Fighting System</option>

</optgroup>
<optgroup label="Process Plant Safety System" id="ss_2">
<option value="Emergency ShutDown System">ESD System</option>
<option value="Pressure Safety Valve">Pressure Safety Valve</option>
<option value="LSHH, LSLL, PSHH, PSLL, TSHH, TSLL">LSHH, LSLL, PSHH, PSLL, TSHH, TSLL</option>

Hi Zul,

Are you using the updated version of the tutorial from here? The one in the book didn't work in all browsers :-(
