Hi,
I'm new to CakePHP, OOP and my PHP knowledge & skills could probably be
considered beginner++ level, so please have patience with me.
I'm producing an event registration system for a festival website. I have
created a multi-step form that uses a session to temporarily record data.
It asks users to specify the ideal audience for their event, based upon
age. This needs to allow multiple selections, and I want to collate and
write their selections into a single mySQL database text field called
'audience'.
The code I'm using to create the multiple selections in my form view is as
follows (actual form has several more options)
$options = array('5-7' => '5-7 years', '7-11' => '7-11 years', '11-14' =>
'7-11 years');
echo $this->Form->select('audience', $options, array('multiple' =>
'checkbox'));
This generates the following HTML:
<input type="hidden" name="data[Proposal][audience]" value=""
id="ProposalAudience"/>
<div class="checkbox"><input type="checkbox"
name="data[Proposal][audience][]" value="5-7" id="ProposalAudience57"
/><label for="ProposalAudience57">5-7 years</label></div>
<div class="checkbox"><input type="checkbox"
name="data[Proposal][audience][]" value="7-11" id="ProposalAudience711"
/><label for="ProposalAudience711">7-11 years</label></div>
<div class="checkbox"><input type="checkbox"
name="data[Proposal][audience][]" value="11-14" id="ProposalAudience1114"
/><label for="ProposalAudience1114">11-14 years</label></div>
The code I'm using in my controller file to write to the database is as
follows:
$arrAudience = $this->Session->read('form.data.audience');
$strAudience = implode($arrAudience);
$this->Session->write('form.data.audience', $strAudience);
$this->Proposal->save($currentSessionData);
But I get the following errors:
Warning (2): implode() [function.implode]: Argument must be an array
[APP/Controller/ProposalsController.php, line 106]
Notice (8): Array to string conversion
[CORE/Cake/Model/Datasource/DboSource.php, line 1009]
The SQL query dump has the word 'Array' where I'd expect my string to be.
Where am I going wrong? Should I be using something other than the basic
PHP implode function?
Thanks for any help you can give.
