    <p>Hello guys I have a problem with my code. Because I want to create a tool for updating google maps. But my data is in txt file not in database. That's why I am having a hard time coding it. Ok the scenario is:</p> <ol> <li>The user will locate it's new location</li> <li>After that, the user will click UPDATE and the program will write a txt file and a csv as well</li> <li>Now the condition is if the user update the map (meaning existing ID) in the txt file or csv. Instead of adding new updated location. It will update only.</li> </ol> <p>Here's my code.</p> <pre><code>if ($_SERVER['REQUEST_METHOD'] == 'POST') { $post_data = $_POST; if (!empty($post_data['company_id']) &amp;&amp; !empty($post_data['new_lat']) &amp;&amp; !empty($post_data['new_long'])) { // Save $restaurant_id = $post_data['company_id']; $new_lat_entry = $post_data['new_lat']; $new_long_entry = $post_data['new_long']; $datenow = date_create(); $timestamp = $datenow-&gt;format('U'); //THIS WILL CREATE ARRAY OF NEW DATA $data_add = array( 'restaurant_id' =&gt; $restaurant_id, 'new_lat' =&gt; $new_lat_entry, 'new_long' =&gt; $new_long_entry, 'date_updated' =&gt; $timestamp ); //GET THE EXISTING TXT FILE AND UNSERIALIZE IT $data = unserialize(file_get_contents('addresses.txt')); $data[] = $data_add; //ADD LATEST DATA TO ARRAY //SERIALIZE UPDATED ARRAY $serialize_data = serialize($data); file_put_contents("addresses.txt", $serialize_data, LOCK_EX); //write the text file //WRITE UPDATE OR NEW txtfile $array = unserialize(file_get_contents('addresses.txt')); //CREATE CSV $file_input = fopen("addresses.csv","w"); foreach ($array as $row) { fputcsv($file_input, $row); } fclose($file_input); } else { // prompt missing inputs } </code></pre> <p>What function do I need to use for that? That's all guys thanks.</p>

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.
