Ask the form array problem

joyoyj

while($r=mysql_fetch_array($result))
{
    $fid =$r["id"];
    $fname =$r["name"];
    $finfo =$r["info"];

echo "<tr><td align=\"right\" width=5%><input type=\"checkbox\" name=\"selforum[]\" value=\"$fid\" /></td>
      <td align=\"left\" width=20%><input type=\"text\" name=\"fname[]\" value=\"$fname\" size=\"20\" /></td>
      <td align=\"left\" width=65%><input type=\"text\" name=\"finfo[]\" value=\"$finfo\" size=\"60\" /></td>< /tr>";
}
echo "<tr><th colspan=\"3\">
      <a href=\"\"><input type=\"button\" value=\"新\" /></a>&nbsp;&nbsp;&nbsp;
      <a href=\"updateForum.php\"><input type=\"button\" value=\"Update\" /></a>&nbsp;&nbsp;&nbsp;
      <a href=\"delForum.php\"><input type=\"button\" value=\"delete\" onClick=\"check()\" /></a></th></tr>" ;
echo "</table>";


When clicking "update" "delete", how should this dynamically generated form be delivered????

When you click "New", a line is generated below <checkbox> <text> <text>, how to write this???

Just like what you wrote on the page, you can get it by name.

joyoyj

updateForum.php////////////////

for($i=0;$i<$selforum.length;$i++)
{
    if($selforum['$i'].checked)
    {
$forumid =$_POST[selforum['$i'].value"];
$forumname=$_POST[fname['$i']];
$foruminfo=$_POST[finfo['$i']];
   
Is this? But there is an error

joyoyj

$forumid =$_POST[selforum['$i'].value];

The above is wrong

$foruminfo=$_POST['finfo[]']; Get the array like this

Forgot whether to quote the quotes in $_POST[], his name is finfo[]

joyoyj

$foruminfo=$_POST['finfo[]']; Get the array like this

===============

Thanks a lot, try

joyoyj

$foruminfo=$_POST['finfo[]']; Get the array like this

Can not do it

$foruminfo = $_POST["finfo"];
        $n = count($foruminfo);
        for($i=0;$i<$n;$i++) {
            echo $foruminfo$i];
        }

$i = 0;
while($r=mysql_fetch_array($result))
{
    $fid =$r["id"];
    $fname =$r["name"];
    $finfo =$r["info"];

echo "<tr><td align=\"right\" width=5%><input type=\"checkbox\" name=\"selforum[$i]\" value=\"$fid\" /></td>
      <td align=\"left\" width=20%><input type=\"text\" name=\"fname[$i]\" value=\"$fname\" size=\"20\" /></td >
      <td align=\"left\" width=65%><input type=\"text\" name=\"finfo[$i]\" value=\"$finfo\" size=\"60\" /></td ></tr>";
}


The program part can only be written in this way to distinguish each fname corresponding to its own finfo when receiving data
Otherwise it is impossible to determine which forum needs to be updated
Use $_POST['selforum'],$_POST['fname'],$_POST['finfo'] when receiving
Then foreach()
