How to insert data to database from multiple select dropdown in codeigniter? - php

Question

I have drop down which is look like the following
<select class="selectpicker form-control" multiple name="category[]">
<option value="1" id="MENTAL HEALTH">MENTAL HEALTH</option>
<option value="2" id="SUICIDE SUPPORT">SUICIDE SUPPORT</option>
<option value="3" id="HEALTH">HEALTH</option>
<option value="4" id="SUPPORT">SUPPORT</option>
</select>
In my controller I have the following code to get that data from the dropdown
public function save()
{
$ctgry= ($this->input->post('category'));
$orgName= ($this->input->post('InputName'));
$streetNo= ($this->input->post('StreetNo'));
$streetName= ($this->input->post('StreetName'));
$suburb= ($this->input->post('Suburb'));
$state= ($this->input->post('state'));
$postCode= ($this->input->post('PostCode'));
$count = count($ctgry);
$supprtGroup = array(
'name' => $orgName,
'street_no' => $streetNo,
'street' => $streetName,
'suburb' => $suburb,
'state' => $state,
'pc' => $postCode
);
$supportgroup_id = $this->Home_Model->addSupportGroup($supprtGroup);
$j = 0;
i = 0;
$sc_id = 0
echo 'aa';//just for error checking purpose
if ($count > 1)
{
echo ' aa1';//just for error checking purpose
while ($i > $count)
{
echo ' aa2';//just for error checking purpose
$support_category = array(
'supportgroup_id' => $supportgroup_id,
'category_id' => $ctgry[$j]
);
$sc_id = $this->Home_Model->addSupportrCategory($support_category);
$i++;
echo $sc_id;//just for error checking purpose
}
}
else
{
echo ' aa3';//just for error checking purpose
$support_category = array(
'supportgroup_id' => $supportgroup_id,
'category_id' => $ctgry[$j]
);
$sc_id = $this->Home_Model->addSupportrCategory($support_category);
echo $sc_id;//just for error checking purpose
}
echo'bb';//just for error checking purpose
}
The following is my model class
function addSupportGroup($supprtGroup=NULL)
{
$this->db->insert('support_group', $supprtGroup);
return $this->db->insert_id();
}
function addSupportrCategory($support_category=NULL)
{
$this->db->insert('support_category', $support_category);
return $this->db->insert_id();
}
When select multiple values from dropdown the out put as follows
aa aa1bb
Could anyone give me an answer why this is happening, if it is a single value
selected from the dropdown its saving to the DB fine I search every similar
posts but couldn't find the answer.

Answer 1

I can't see where $count is defined in your question so I don't know what it's value is meant to be, however, if you are getting "aa1" as output you are saying that it's bigger than 1.
With your while() you're saying that $i must be bigger than $count but $i equals 0 so therefore the while loop won't start.
If you are just wanting to loop through the categories it would be easier to just:
$supportgroup_id = $this->Home_Model->addSupportGroup($supprtGroup);
foreach ($ctgry as $cat) {
$insert = array(
'supportgroup_id' => $supportgroup_id,
'category_id' => $cat
);
$sc_id = $this->Home_Model->addSupportrCategory($support_category);
}
This will work because the dropdown will always be picked up as an array.
You should also look at adding some validation to this!
Hope this helps!
