how to insert multiple data from looped table? - php

Question

I want to insert multiple records from a looped table. Each row have hidden inputs.
I will POST the total number of rows for the table which will be used in the loop condition.
Here is my view:
<input type="hidden" name="rowcount">//total row of the table
<table class="table" id="ctable" style="border:0;">
<?php
foreach ($row12 as $row12) {
echo"<tr>
<td style='vertical-align:midle; width:175px; border:0; padding-right:20px;' align='right' ><b>".$row12->mapel_un."</b></td>
<td style='border:0;'>
<input type='hidden' name='id_peserta' value='$row13->id_peserta'>
<input type='hidden' name='id_un' value='$row12->id_un'>
<input class='form-control' type='text' name='nilai' value='$nilai' />
</td>
</tr>";
}
?>
</table>
Here is my model:
function simpan_nilai(){
$jumlah = $this->input->post('rowcount');
$x=1;
while($x<=$jumlah){
$this->db->query("INSERT INTO nilai SET
id_peserta = '".$this->input->post('id_peserta')."',
id_un = '".$this->input->post('id_un')."',
nilai = '".$this->input->post('nilai')."' ");
$x++;
}
return "info-Data berhasil disimpan ...";
}
I've only been able to insert the last row of data. For example, if the data is like (001, 1, 100), (001, 2, 90), (001, 3, 95), only the last row of record is inserted into the database i.e. (001, 3, 95).
Please help me. Thanks!

The reason is because you have multiple hidden inputs of the same name id_peserta. In your PHP codes, the only input that is received is the last input of the same name.
You can try to append a count after each of your input name to make it unique.
<input type="hidden" name="rowcount"> <!-- total row of the table -->
<table class="table" id="ctable" style="border:0;">
<?php
$count = 1; // You can start from zero. Either works.
foreach ($row12 as $row12) {
echo "<tr>
<td style='vertical-align:midle; width:175px; border:0; padding-right:20px;' align='right' ><b>".$row12->mapel_un."</b></td>
<td style='border:0;'>
<input type='hidden' name='id_peserta{$count}' value='$row13->id_peserta'>
<input type='hidden' name='id_un{$count}' value='$row12->id_un'>
<input class='form-control' type='text' name='nilai{$count}' value='$nilai' />
</td>
</tr>";
$count++;
}
?>
</table>
And for your PHP codes.
function simpan nilai(){
$jumlah = $this->input->post('rowcount');
$x=1;
while($x<=$jumlah){
$this->db->query("INSERT INTO nilai SET
id_peserta = '".$this->input->post('id_peserta' + $x)."',
id_un = '".$this->input->post('id_un' + $x)."',
nilai = '".$this->input->post('nilai' + $x)."' ");
$x++;
}
return "info-Data berhasil disimpan ...";
}
