I'm trying to use an array to determine the colors in a table... However, I believe my syntax is incorrect...
Array :
$colors = [
1 => "red",
2 => "yellow",
3 => "green",
];
HTML/PHP :
<td bgcolor=\"$colors[$row['form1']]\">".$row["form1"]."</td>
Any help is appreciated, thanks!
Try the below
$doc= new DOMDocument(); $doc->loadHTML($html); $colors = array(1 => "red",2 => "yellow",3 => "green");foreach ($doc->getElementsByTagName('td') as $td) {if ($td->getAttribute('bgcolor'),$colors) { /* if true then any color in the array is equal to the td's bgcolor*/ } }
Try this:
<?php echo '<td bgcolor="'.$colors[intval($row['form1'])].'">'.$row["form1"].'</td>'; ?>
Try This code will work for
<?php
$colors = array(1 => "red", 2 => "yellow", 3 => "green");
$form1=1;
?>
<table border="1">
<thead>
<td>name</td>
<td>Class</td>
</thead>
<tbody>
<tr>
<td bgcolor='<?php echo $colors[$form1]; ?>'>test</td>
<td>bcs</td>
</tr>
<tr>
<td>temp</td> <td>mcs</td>
</tr>
</tbody>
</table>
change $form1 varibale value dynamicaly as you want.
try this bro.
<?php
$colors = array(
1 => "red",
2 => "yellow",
3 => "green",
);
?>
<html>
<body bgcolor="<?php $row["form1"]=1;// replace it . i have assigned it as 1
$r=$row["form1"];
echo $colors[$r];?>"><?php echo $r; ?>
</body>
</html>
First check array is created in right way means there is any error in it....and $row['form1'] value is in correct format
to print array print_r($colors);exit;
after that this will work
$colors = array(1=>"red",2 => "yellow",3 => "green");
<tr>
<td bgcolor="<?php echo $colors[2];?>"><?php echo $colors[2]; ?></td>
</tr>
Please try in this way :
<td bgcolor="<?php echo $colors[$row['form1']]; ?>"><?php echo $row['form1']; ?></td>
First create an array
$colors = array("a" => "red", "b" => "yellow","c" => "green");
HTML code with PHP
<td bgcolor="<?php echo $colors['a'];?>"> <?php echo $row['form1'] ?> </td>
Hope this will help you.
