    <p>I need to insert elements of a php encoded array into a database and I'm completely stuck. I have first used json encode to to grab data from the database using an SQL query (which I did successfully) but I now need to be able to do the opposite. If anyone could help I'd greatly appreciate it. It's my second day of work and I'm not doing so well. The following is my code:</p> <pre><code> $UserCoords_Query = "Select Accuracy, Longitude, Latitude, Timestamp FROM UserDetails WHERE UserId =" . $UserID; $UserCoords_result = mysql_query($UserCoords_Query); if (mysql_num_rows($UserCoords_result) == 0) { echo "There are no users with an id of ". $UserID; } else { $EmptyArray=array(); while ($row = mysql_fetch_array($UserCoords_result)) { $Accuracy=$row['Accuracy']; $Longitude= $row['Longitude']; $Latitude=$row['Latitude']; $Timestamp= $row['Timestamp']; $Queue= array('Accuracy:' =&gt; $Accuracy, 'Latitude' =&gt; $Latitude, 'Longitude' =&gt; $Longitude, 'Timestamp' =&gt; $Timestamp); array_unshift($EmptyArray,$Queue); } $ObjectResponse = array('Coords' =&gt; $EmptyArray); echo json_encode($ObjectResponse); $Json_Encoded= json_encode($ObjectResponse); $Json_Decoded= json_decode($Json_Encoded, true); $Update_Query= "INSERT INTO UserDetails (UserId, Accuracy, Latitude, Longitude, Timestamp) VALUES ('".$UserID."','".$Json_Decoded[0] ['Accuracy']."','".$Json_Decoded[0]['Latitude']."', '".$Json_Decoded[0]['Longitude']."','".$Json_Decoded[0]['Timestamp']."')"; mysql_query($Update_Query) or die(mysql_error()); </code></pre>

    2. COyou shouldn't be inserting json text into a db, unless you plan to NEVER access any individual sub-data from the json text with sql. json's a transport format, not a storage format.

    3. CO@ Marc B Well I'd need to explode the string to get the elements and add them to the DB. I thought that was what the json decode function does?

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.
