PHP Fetch array in table with individual styling - php

Question

I have an array that i pull from a database that looks like this
id - name - shortlink - downloadurl - count - date
Now I want to display that array as a table so the administartor of the site can se the content of the database. For that, I'm using this code:
function build_table($array){
// start table
$html = '<table id="usertable">';
// header row
$html .= '<tr class="header">';
foreach($array[0] as $key=>$value){
$html .= '<th>' . $key . '</th>';
}
$html .= '</tr>';
// data rows
foreach( $array as $key=>$value){
$html .= '<tr>';
foreach($value as $key2=>$value2){
$html .= '<td>' . $value2 . '</td>';
}
$html .= '</tr>';
}
// finish table and return it
$html .= '</table>';
return $html;
And it works great.
The problem is that i wan't do display some of the columns with a different code. E.g. 'downloadurl' which is an webadress, i want to make clickable. I just can't figure out how to split up the function so that i can write the code for the individual columns.

Answer 1

You could try something similar to the following:
using conditionals
This is probably the most straight forward way to go about handling different attributes per column - not without its drawbacks (noted below)
// data rows
foreach( $array as $key => $value) {
$html .= '<tr>';
foreach($value as $key2 => $value2) {
if ($key2 == 'downloadurl') {
$html .= '<td>Download</td>';
} else {
$html .= '<td>' . $value2 . '</td>';
}
}
$html .= '</tr>';
}
using switch statement
If you decide on this route, it may be a bit easier to manage in the long run as if () elseif () else() can become difficult to read over time.
foreach($value as $key2 => $value2) {
switch($key2) {
case 'downloadurl':
$html .= '<td>Download</td>';
break;
default:
$html .= '<td>' . $value2 . '</td>';
}
}

Answer 2

use this function to generate urls:
function getURL($downloadURL)
{
$html = "<a href = '$downloadURL'>Download</a>";
return $html;
}
And your function build_table():
function build_table($array){
// start table
$html = '<table id = "usertable">';
// header row
$html .= '<tr class = "header">';
foreach($array[0] as $key => $value){
$html .= '<th>' . $key . '</th>';
}
$html .= '</tr>';
// data rows
foreach( $array as $key => $value){
$html .= '<tr>';
foreach($value as $key2 => $value2){
$value2 = ($key2 == 'downloadurl') ? getURL($value2) : $value2;
$html .= '<td>' . $value2 . '</td>';
}
$html .= '</tr>';
}
// finish table and return it
$html .= '</table>';
return $html;
}
