[SOLVED]List box with multiple selection

kokomo:

In your controller replace the call to
mb_strlen(array("9","10"),"UTF-8");
with my foreach loop i suggested.

[size="2"]Again, you could not pass an array to mb_strlen as first parameter.[/size]

For testing purpose you could also simply comment the call to mb_strlen out to test if you have error’s somewhere else.

I dont have such a line in my controller.


mb_strlen(array("9","10"),"UTF-8");

i was just telling about my error when i try executing it.

What is the function that gives you the error?

Are you sure that the beforeSave succeded and converted the array to a string before calling this function?

Are you sure that you have not some stuff like length validator on the field?

Try douing a bit of debug, and understand what is calling mb_strlen on this array.

Everything started working but now problem is storing it in db

I am getting the value like this inside db

why so??

emil_pgc · July 1, 2011, 11:14am

Inside model i have given in rules for skillid field like dis


array('mobilenumber,companyname,name,email,factorylocation,skillid','required')

i hope that is not the prob

You save the data serialized

http://php.net/manual/en/function.serialize.php

following Zaccaria’s instructions




//serialize the data before save to database

public function beforeSave()

{

    $this->skillid= serialize($this->skillid);

    return parent::beforeSave();

}

//transform the serialized data back into its normal form after find

public function afterFind()

{

    $this->skillid= unserialize($this->skillid);

    return parent::afterFind();

}

}

By following his words only it was possible to do…

But why is the data getting stored like that??

is it the way it gets stored while using serialization?

emil_pgc · July 1, 2011, 3:43pm

Anyway i have started using json_encodeinstead of serialization…

If you want to store a string like "9,10" you can use the PHP function implode() and explode()…

emil_pgc · July 1, 2011, 3:52pm

i am trying on implode now…




public function beforeSave()

{

   $this->skillid= implode (',',$this->skillid);

    return parent::beforeSave();

}

but giving a error implode() [<a href=‘function.implode’>function.implode</a>]: Invalid arguments passed

Even though this error is shown all my data is getting stored properly in db…

Can someone help me out… why is this error coming??

emil_pgc · July 2, 2011, 1:38pm

Guys i fixed it with a crooked way… i just removed the error msg from the code…

softark · July 2, 2011, 2:14pm

What do you mean by that?

What line(s) did you remove from what source file?

emil_pgc · July 2, 2011, 2:18pm

i just removed a single line from my order form


<?php echo $form->error($model,'skillid'); ?>

So no error will be coming…

Actual Problem Now

It gives you an error when ‘skillid’ is empty, therefore you should use @ or test the variable, like


if(!empty($this->skillid))

	$this->skillid=implode(',',$this->skillid);

and after do that, continue using the error field

Great… Thank you… It’s working…
