How to combine two SQL tables in codeigniter without using SQL queries? - php

Question

Here is my codes,
//FROM MY CONTROLLER
$companies = $this->Uploads_model->getallcompanies();
$general = $this->Uploads_model->getallcontract();
$this->data['companieslist'] = $companies;
$this->data['uploads'] = $general;
$this->render('contracts/index_view');
// MY VIEW
foreach($companieslist as $company){
$general_c[] = $company->company_id;
$general_c[] = $company->company_name;
}
foreach ( $uploads as $key => $con ) {
?>
<tr>
<td class="center">
<label class="pos-rel">
<input type="checkbox" class="ace"/>
<span class="lbl"></span>
</label>
</td>
<td>
<a href="#">
<?php
if($con->Company_id == $general_c[$company_id]){ // MY QUESTION IS HERE
echo $con->Company_name;
}
?>
</a>
</td>
So, am working on this web app where am supposed to display in table all contract files followed with company owned this contract.
I have two tables in my Database as follow Companies_tbl and contract_tbl.
I have Company_id as a foreign key in contract_tbl.

Answer 1

Create a custom function to filter your contracts based on Company_id
function getContractsForId($contracts,$Company_id) {
return array_filter($contracts,function(){
return $contracts->Company_id === $Company_id;
});
}
template loop:
foreach( getContractsForId($uploads,$Company_id) as $key => $con) {
//...html...
//remove the if
}

Answer 2

You are not building the array of companies the right way.
foreach($companieslist as $company){
$general_c[] = $company->company_id;
$general_c[] = $company->company_name;
}
After you looped once, the $general_c array will look like this:
$general_c = [
0 => 1, //company id
1 => 'Company name'
]
After the second time:
$general_c = [
0 => 1, //company id
1 => 'Company name',
2 => 2, //company id
3 => 'Company name 2'
]
What you want is the following:
foreach($companieslist as $company){
$general_c[$company->company_id] = $company->company_name;
}
And below:
<?php
if($general_c[$con->Company_id]) {
echo $general_c[$con->Company_id];
} ?>
This will let you output the company name based on ID.
But i suggest you do a MySQL join in your model. Add something like this to your Uploads_model:
function getContractsWithCompany() {
$query = $this->db->select('*')
->from('contract_tbl')
->join('Companies_tbl', 'Companies_tbl.id = contract_tbl.Company_id')
->get();
return $query->result();
}

Answer 3

You need first to group files by Company_id then list the specific company files
$companies = $this->Uploads_model->getallcompanies();
$general = $this->Uploads_model->getallcontract();
$this->data['companieslist'] = $companies;
$this->data['uploads'] = array();
//group file list by Company_id
foreach ($general as $key => $file) {
if(!isset($this->data['uploads'][$file->Company_id ]))
$this->data['uploads'][$file->Company_id] = array();
$this->data['uploads'][$file->Company_id][] = $file;
}
// in your view
foreach($companieslist as $company){
$general_c[] = $company->company_id;
$general_c[] = $company->company_name;
if(isset($uploads[$company->company_id])) {
foreach ( $uploads[$company->company_id] as $key => $con ) {
?>
<tr>
<td class="center">
<label class="pos-rel">
<input type="checkbox" class="ace"/>
<span class="lbl"></span>
</label>
</td>
<td>
<?=$company->company_name?>
</td>
</tr>
<!-- and the rest of logic -->
<?php
}
}
}
