Reply to reading variables?

Your name:


Posted by "William Stokes" on 01/20/06 07:46


The code below is from a document library I'm building. With this user can
upload a file to server and the uploaded files are printed as links to same
page. For each printed document there's a check box "Delete" for marking
that document for deletion. The document info from DB is printed using
'while' loop. The only problem I have is that I don't know how to
handle/read the Delete checkbox values because the checkbox name is
different for each file. Checkboxes are printed whit this line:"echo "<td
colspan=\"5\"><input type=\"checkbox\" name=\"del_$id\">Delete</td>";"

So. Any ideas how to resolve this or find another way to do the same task?
I'm running out of ideas. Thanks a lot! (Please see code below)



/* if document is marked for deletion run delete code here. HOW?*/

/*start the form*/
print "<form name=\"docs\" method=\"post\" action=\"$PHP_SELF\"

/*select the old docs from DB*/

$sql="SELECT * FROM ******* ";
$num = mysql_num_rows($result);
$cur = 1;
while ($num >= $cur) {
$row = mysql_fetch_array($result);
$id = $row["id"];

/*put results to vars here*/

echo "<table width=\"700\" border=\"0\" cellspacing=\"0\"

/*print data out here */

/*mark checkbox below if you want to delete the document. $id is documents
id from database*/

echo "<tr>";
echo "<td colspan=\"5\"><input type=\"checkbox\"
echo "</tr>";

/*print rest of data out here */

echo "</table>";
