Fearpig Posted May 5, 2013 Share Posted May 5, 2013 Hello,I need help updating multiple rows at once Table Columns:Model_ID, Image I want to update all rows where the image field is empty to have a value of: 'data/Products/' . $model . '.jpg' I can update one row at a time but I want to upload things in a batch! I've written a select page <html> <body> <?php //Conntect to Database include 'Database_Connection.php'; if ($db_found) { //print "<i>Database Found (" . $db_handle.")</i></br></br>"; $SQL = "SELECT * FROM `oc_product` WHERE image = ''"; $result = mysql_query($SQL); $x = 1; echo "<table class='Data'><thead><tr><th>Model</th><th>Image</th><th>Image Should Be...</th></tr></thead><tbody>"; while ($db_field = mysql_fetch_assoc($result)){ $model = $db_field['model']; $image = $db_field['image']; $image_should_be = 'data/Products/' . $model . '.jpg'; if ($x < 0){ $Table_Row = 'Row_Style1'; } else { $Table_Row = 'Row_Style2'; } print " <tr class='$Table_Row'> <td>$model</td> <td>$image</td> <td>$image_should_be</td> </tr>"; $x = $x * (-1); } echo "</table>"; } else { echo "Whoops!"; } echo "<a href=Update_Images.php>Update</a>"; ?> </body> </html> My database connection is fine as the user has the correct permissions but when I try to update the images I'm getting something wrong and the records are not updating or giving me an error message. My idea was to loop through the records using a select query and then update each record. <html> <body> <?php //Conntect to Database include 'Database_Connection.php'; if ($db_found) { //print "<i>Database Found (" . $db_handle.")</i></br></br>"; $SQL = "SELECT * FROM `oc_product` WHERE image = ''"; $result = mysql_query($SQL); while ($db_field = mysql_fetch_assoc($result)){ $model = $db_field['model']; echo "$model<br>"; $image_should_be = 'data/Products/' . $model . '.jpg'; $SQL_UPDATE = "UPDATE `oc_product` SET image = '$image_should_be' WHERE model = $model"; $result_update = mysql_query($SQL_UPDATE); } } else { echo "Whoops!"; } echo "<a href=test.php>Test</a>"; ?> </body> </html> I added in the... echo "$model<br>"; ...just to see if the page was doing anything and I now get a list of model numbers but no updates in the table.

Barand Posted May 5, 2013 Share Posted May 5, 2013 $image_should_be = 'data/Products/' . $model .

Barand Posted May 5, 2013 Share Posted May 5, 2013 I meant to post this - you could do the whole table with a single query with mysql_query("UPDATE `oc_product` SET image = CONCAT('data/Products/' , model, '.jpg') WHERE image = '' "); Link to comment https://forums.phpfreaks.com/topic/277680-update-multiple-rows/#findComment-1428492 Share on other sites More sharing options...
