    <p>I am creating a JQuery cycle for weather radar and warning images. I have the radar overlay functioning just fine. The directory containing the warning files contains 2 versions of each file but one has a similiar file names as the radar images. So I decided to use a str_replace to replace the one part of the filename from the radar images to the warning images. For some reason the str_replace is not working and I cannot for the life of me figure out why.</p> <p>Thank you in advance for any help.</p> <pre><code>// Used to get radar images echo '&lt;div class="wp-forecast-img-cur"&gt;'."\n"; $matches = array(); preg_match_all("/(a href\=\")([^\?\"]*)(\")/i", get_text('http://radar.weather.gov/ridge/RadarImg/N0R/BOX/'), $matches); foreach($matches[2] as $k =&gt; $match) { if ($k &lt; 1) continue; echo '&lt;img src="http://radar.weather.gov/ridge/RadarImg/N0R/BOX/' . $match . '" /&gt;'."\n"; } echo '&lt;/div&gt;'."\n"; // Used to get warning images echo '&lt;div class="wp-forecast-img-warn"&gt;'."\n"; $matches = array(); preg_match_all("/(a href\=\")([^\?\"]*)(\")/i", get_text('http://radar.weather.gov/ridge/RadarImg/N0R/BOX/'), $matches); foreach($matches[2] as $k =&gt; $match) { if ($k &lt; 1) continue; echo '&lt;img src="http://radar.weather.gov/ridge/Warnings/Short/BOX/' . str_replace("NOR", "Warnings", $match) . '" /&gt;'."\n"; } echo '&lt;/div&gt;'."\n"; </code></pre> <p>This line is just echoing the original file name and not replacing NOR with Warnings.</p> <pre><code>echo '&lt;img src="http://radar.weather.gov/ridge/Warnings/Short/BOX/' . str_replace("NOR", "Warnings", $match) .

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
