Question

We have a basic PHP script to extract the title and description for each job from a MySQL database as simply display this information. This is what it looks like:

$sql        = "SELECT `title`, `desc` FROM jobs WHERE active = 'y'";
$query      = mysql_query($sql) or die('<em><strong>SQL Error:</strong> ' . mysql_error() . '</em>');
$results    = mysql_fetch_assoc($query);

<?php while($result = mysql_fetch_assoc($query)) {
    echo '<div class="left_content" style="margin-top: 15px;">';
    echo "<h2>{$results['title']}</h2>";
    echo "<p>{$results['desc']}</p>";
    echo '</div>';
} ?>

Now, this only extracts one row from the database, but it should extract two. So, I tried the following to replace the while statement:

<?php foreach($results as $result) {
    echo '<div class="left_content" style="margin-top: 15px;">';
    echo "<h2>{$result['title']}</h2>";
    echo "<p>{$result['desc']}</p>";
    echo '</div>';
} ?>

This statement doesn’t work either. This just displays (weirdly) the first character of each column in the first row in the table.

Does anyone have any idea as to why this isn’t working as it should?

Result variable you have used is result not results

Replace

$sql        = "SELECT `title`, `desc` FROM jobs WHERE active = 'y'";
$query      = mysql_query($sql) or die('<em><strong>SQL Error:</strong> ' . mysql_error() . '</em>');
**$results    = mysql_fetch_assoc($query);** // remove this line

<?php while($result = mysql_fetch_assoc($query)) {
    echo '<div class="left_content" style="margin-top: 15px;">';
    echo "<h2>{$results['title']}</h2>";
    echo "<p>{$results['desc']}</p>";
    echo '</div>';
} ?>

to

$sql        = "SELECT `title`, `desc` FROM jobs WHERE active = 'y'";
$query      = mysql_query($sql) or die('<em><strong>SQL Error:</strong> ' . mysql_error() . '</em>');


<?php while($result = mysql_fetch_assoc($query)) {
    echo '<div class="left_content" style="margin-top: 15px;">';
    echo "<h2>{$result['title']}</h2>";
    echo "<p>{$result['desc']}</p>";
    echo '</div>';
} ?>
