How to embed icons inside an HTML table obtained from a csv? - php

Question

The php code below extracts the data from a .csv file and generates an HTML table. It works fine. I wonder if it is possible to embed in the html table some icons, such as a red or green dot (reddot.gif , greendot.gif) in correspondence of some specific words (example: red , green) in the csv file.
In other words, when in the csv file appear red or green in a specific column (example: column 3), should appear the reddot.gif or greendot.gif in the generated html file.
Thanks in advance. Mat
<?php
$row = 1;
if (($handle = fopen("example.csv", "r")) !== FALSE) {
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
$num = count($data);
if ($row == 1) {
echo '<tr>';
}else{
echo '<tr>';
}
for ($c=0; $c < $num; $c++) {
if(empty($data[$c])) {
$value = " ";
}else{
$value = $data[$c];
}
if ($row == 1) {
// ------------- head row --------
echo '<td style="border-top: 1px solid rgb(111,180,224); border-left: 1px solid rgb(111,180,224); border-bottom: 1px solid rgb(111,180,224);" align="left" bgcolor="#0066cc" height="36" valign="middle" ><b><font color="#ffffff" size="2"> '.$value.' </font></b></td>';
}else{
// ------------- Generic row -------
echo '<td style=" border-bottom: 1px solid rgb(111,180,224);" sdval="9" sdnum="1040;" align="left" bgcolor="#ffffff" height="25" valign="middle"><font color="#000000" size="2"> '.$value.' </font></td>';
}
}
if ($row == 1) {
echo '</tr>';
}else{
echo '</tr>';
}
$row++;
}
echo '</tbody></table>';
echo '</center>';
fclose($handle);
}
?>

Answer 1

declare this function outside of any loops, just at the beginning of the if, or even at the beginning or ending of the script:
function img($img){ return "<img src='{$img}dot.gif'/>";}
this goes in the else:
$value = preg_replace(array('/red/i', '/green/i'), array(img('red'), img('green')), $data[$c]);
If you need more colors just follow the logic and add them in the two arrays inside of the preg_replace.
If you need to add attributes to the images add them in the function declared.
Hope it works for you

Answer 2

Please give this a try.
if(empty($data[$c])) {
$value = " ";
}else{
$value = $data[$c];
switch(strtolower(trim($value))){
case 'green': $value = '<img src="greendot.gif" '
.'alt="green" height="32" width="32">';
break;
case 'red': $value = '<img src="reddot.gif" '
.'alt="red" height="32" width="32">';
break;
// you can add other cases here like blue, triangle etc :)
}
}
