i have the following code:
<?php
$events = Event::with('skoler')->get();
$skoleIsSet = $_GET['skoleId'];
$eventIsSet = $_GET['event'];
if($skoleIsSet && !$eventIsSet) {
foreach($events as $event) {
if($event['skole_id'] == $skoleIsSet) {
***$img = $event['img_url'];***
echo '<div id="events">';
***echo '<img src="$img" height="100" width="100"/>';***
echo '<h1>' . $event['title'] . '</h1>';
echo '<p>Beskrivelse: ' . $event['description'] . '</p>';
echo '<p>Pris: ' . $event['pris'] . '</p>';
echo '<p>Dato: ' . $event['date'] . '</p></div>';
}
}
}
else {
foreach ($events as $event) {
if ($event['skole_id'] == $skoleIsSet) {
$bg = $event['img_url'];
'<div id="events">';
echo '<h1>' . $event['title'] . '</h1>';
echo '<p>Beskrivelse: ' . $event['description'] . '</p>';
echo '<p>Pris: ' . $event['pris'] . '</p>';
echo '<p>Dato: ' . $event['date'] . '</p></div>';
}
}
?>
I am supposed to show all events, with a picture. The url for the pictures is in the img_url column in my db. What is wrong with line number 8 and 10? The strong font option is not working, but the lines im referring to is marked with 6x *'s.
Thanks!

echo '<img src="$img" height="100" width="100"/>';
You cannot include a variable directly into a string, if you're using single quotes. Either use double quotes (and escape the double quotes inside the string), or interrupt your string:
echo '<img src="' . $img . '" height="100" width="100"/>';
echo "<img src=\"$img\" height=\"100\" width=\"100\"/>";
