GROUP_CONCAT in CodeIgniter
- by mickaelb91
I'm just blocking to how create my group_concat with my sql request in CodeIgniter.
All my queries are listed in a table, using Jtable library.
All work fine, except when I try to insert GROUP_CONCAT.
Here's my model page :
function list_all()
{
$login_id = $this->session->userdata('User_id');
$this->db->select('p.project_id, p.Project, p.Description, p.Status, p.Thumbnail, t.Template');
$this->db->from('assigned_projects_ppeople a');
$this->db->where('people_id', $login_id);
$this->db->join('projects p', 'p.project_id = a.project_id');
$this->db->join('project_templates t', 't.template_id = p.template_id');
$this->db->select('GROUP_CONCAT(u.Asset SEPARATOR ",") as assetslist', FALSE);
$this->db->from('assigned_assets_pproject b');
$this->db->join('assets u', 'u.asset_id = b.asset_id');
$query = $this->db->get();
$rows = $query->result_array();
//Return result to jTable
$jTableResult = array();
$jTableResult['Result'] = "OK";
$jTableResult['Records'] = $rows;
return $jTableResult;
}
My controller page :
function listRecord(){
$this->load->model('project_model');
$result = $this->project_model->list_all();
print json_encode($result);
}
And to finish my view page :
<table id="listtable"></table>
<script type="text/javascript">
$(document).ready(function () {
$('#listtable').jtable({
title: 'Table test',
actions: {
listAction: '<?php echo base_url().'project/listRecord';?>',
createAction: '/GettingStarted/CreatePerson',
updateAction: '/GettingStarted/UpdatePerson',
deleteAction: '/GettingStarted/DeletePerson'
},
fields: {
project_id: {
key: true,
list: false
},
Project: {
title: 'Project Name'
},
Description: {
title: 'Description'
},
Status: {
title: 'Status',
width: '20px'
},
Thumbnail: {
title: 'Thumbnail',
display: function (data) {
return '<a href="<?php echo base_url('project');?>/' + data.record.project_id + '"><img class="thumbnail" width="50px" height="50px" src="' + data.record.Thumbnail + '" alt="' + data.record.Thumbnail + '" ></a>';
}
},
Template: {
title: 'Template'
},
Asset: {
title: 'Assets'
},
RecordDate: {
title: 'Record date',
type: 'date',
create: false,
edit: false
}
}
});
//Load person list from server
$('#listtable').jtable('load');
});
</script>
I read lot of posts talking about that, like replace ',' separator by ",", or use OUTER to the join, or group_by('p.project_id') before using get method, don't work.
Here is a the output of the query in json :
{"Result":"OK","Records":[{"project_id":"1","Project":"Adam & Eve : A Famous Story","Description":"The story about Adam & Eve reviewed in 3D Animation movie !","Status":"wip","Thumbnail":"http:\/\/localhost\/assets\/images\/thumb\/projectAdamAndEve.png","Template":"Animation Movie","assetslist":"Apple, Adam, Eve, Garden of Eden"}]}
We can see the GROUP_CONCAT is here (after "assetslist"), but the column stills empty.
If asked, I can post the database SQL file.
Thank you.
