    thanks, solved by if($valid_file) { //move it to where we want it to be $target_path = "/home/sites/xxxxxx.co.uk/public_html/yourphotos/uploads/"; $target_path = $target_path . basename( $_FILES['photo']['name']); move_uploaded_file($_FILES['photo']['tmp_name'], $target_path); $message = 'Congratulations! Your file was accepted.'; }

    Hi All, I have this issue when upload a file using an uploader i made. For the life of me I cant figure out why it won't write the file.

    I am trying to draw a table dynamically, I need a table that is 5 x 5, i know i'm close quite my code by just can't quite fathom it out. My sql returns 25 results which i want to return 25 cells in a square table. <?PHP $i = 0; while($row = mysql_fetch_assoc($result)) { $i++; ?> <?PHP if($i== 5) { echo '<tr>'; } ?> <td class="right bottom"><?PHP echo $row['GridID']; ?></td> <td class="right bottom"> </td> <td class="right bottom"> </td> <td class="right bottom"> </td> <td class="bottom"> </td> <?PHP if($i== 5) { echo '</tr>'; $i=0; } ?>

    I need to selected the subscriber_Id from another tabled based on an email address, can't seem to work out why this nested select won't work. Can someone help Thanks Sam INSERT INTO `pommo_subscriber_data` ( `data_id` , `field_id` , `subscriber_id` , `value` ) VALUES ( NULL , '1', (SELECT `pommo_subscribers`.`subscriber_id` FROM `pommo_subscribers` WHERE `pommo_subscribers`.`email` = 'samtwilliams23'ORDER BY `pommo_subscribers`.`subscriber_id` DESC), 'SamTEST');

    Hello All, Just working with PHP's snap v1 functions I can use snmpget fine but snmpset produces the following error; Warning: snmpset() [function.snmpset]: No response from 192.....

    Hi All, I am currently developing a PHP serial application and require some help with a serial read problem on windows.

    Hi all, Does anyone know of an effective way of find out whether a user is still logged in and they haven't left? Sam
  10. samtwilliams
    Maybe one way would be to reset the session_save path and parse the contents of those files?

    Morning(at least for me anyway) All, I am currently integrating a facebook/style chat system into my webpage. I am going to build the active user list myself but need a little guidance on how to list my users which are online and how to detect when the have gone. When my users login i store only their userid in a session like many login systems. When they login i could simply add their name to a active_users table, but how would i detect whether they are still alive? Any help would be great. Thanks Sam

    Afternoon All, I can't seem to work this problem out; I have a form that is generated from a sql list and have two inputs as follows; <input type="text" name="suppliernumber[]" id="suppliernumber[]" /> <input name="snomed[]" type="checkbox" id="snomed[]" value="<?php echo $row['VPPID']; ?>" /> Both are fed to my processing files as arrays, i then run the following foreach which uses the VPPID from the post to search in a database using a where clause. The problem comes when i also need to obtain the data from the suppliernumber $_POST if any has been supplied. My php code; foreach ($_POST['snomed'] as $value) { $getRecord_sql = "SELECT vmps.NM AS NM, vmpps.QTYVAL AS QTYVAL, bnf_lookup_subcatagory.BNF_SUBCAT AS BNF_SUBCAT, bnf_lookup_catagory.BNF_CAT AS BNF_CAT FROM bnf_lookup_catagory INNER JOIN bnf_vmp ON bnf_lookup_catagory.BNF_CAT = bnf_vmp.BNF_CAT INNER JOIN bnf_lookup_subcatagory ON bnf_vmp.BNF_SUBCAT = bnf_lookup_subcatagory.BNF_SUBCAT RIGHT OUTER JOIN vmps INNER JOIN vmpps ON vmps.VPID = vmpps.VPID ON bnf_vmp.VPID = vmpps.VPID WHERE VMPPS.VPPID = '$value'"; $getRecord = mssql_query($getRecord_sql); $row = mssql_fetch_array($getRecord); $nm = $row['NM']; $qtyval = $row['QTYVAL']; $BNF_SUBCAT = $row['BNF_SUBCAT']; $BNF_CAT = $row['BNF_CAT']; $SUPPLIER = $_POST['suppliernumber']; array_push($data_array, array($value, $nm, $BNF_CAT, $BNF_SUBCAT, '', $SUPPLIER, '', '1', '', '', '', '', '', '', '', '1', '', '', $qtyval)); } I can't work out how to add the suppliernumber, i know i need another foreach but can't work out how to do it. Hope someone can help. Sam

    Sorted, additional AND. Thanks Keith. Sam
  14. samtwilliams
    Hi Keith, Thanks for your reply, have had a tinker but can not get rid of this error.
  15. samtwilliams
    Build your table on your localhost and then use the export function to grab the SQL code then just simply execute it on your new server. I suggest you have a read on the basics of mysql first, heres a great resource: http://www.tizag.com/mysqlTutorial/ Sam
