Codeigniter aggiornamento batch per casella di controllo
Ho una situazione come questa, voglio aggiornare alcuni dati in cui gli input sono caselle di controllo, mi è stato provato questo codice di seguito. Dati già salvati nel database, ma dati salvati in un'altra riga,
Ad esempio: ho controllato il colore rosso, giallo e grigio per BirdA e ho controllato scuro e blu per BirdD allo stesso tempo. Nel database, il colore per BirdA è stato salvato correttamente, ma per il 2 ° uccello, scuro e blu sono stati salvati su BirdB ( dovrebbe essere salvato su BirdD )
Voglio risolvere il mio problema sopra, quindi i dati dovrebbero essere salvati nel posto giusto nel database. Si prega di controllare il mio codice di seguito:
La mia tabella Db:
=============================================
| birds | red | blue | grey | yellow | dark |
=============================================
| BirdA | 0 | 0 | 0 | 0 | 0 |
| BirdB | 0 | 0 | 0 | 0 | 0 |
| BirdC | 0 | 0 | 0 | 0 | 0 |
| BirdD | 0 | 0 | 0 | 0 | 0 |
=============================================
Visualizza :
<tr>
<td><input type="hidden" name="birds[]" value='<?php echo $dp['birds']; ?>' /><?php echo $dp['birds']; ?></td>
<td><p align='center'><input type="text" name="qtt[]" value='<?php echo $dp['qtt']; ?>' tabindex="2" style="width:30px;" /></td> <td><p align='center'><input type="checkbox" name="red[]" value='1' <?php if($dp['red']==1) { echo " checked=\"checked\""; } ?> /></td>
<td><p align='center'><input type="checkbox" name="blue[]" value='1' <?php if($dp['blue']==1) { echo " checked=\"checked\""; } ?> /></td> <td><p align='center'><input type="checkbox" name="grey[]" value='1' <?php if($dp['grey']==1) { echo " checked=\"checked\""; } ?> /></td>
<td><p align='center'><input type="checkbox" name="yellow[]" value='1' <?php if($dp['yellow']==1) { echo " checked=\"checked\""; } ?> /></td> <td><p align='center'><input type="checkbox" name="dark[]" value='1' <?php if($dp['dark']==1) { echo " checked=\"checked\""; } ?> /></td>
</tr>
E il controller:
$birds= $this->input->post("birds");
if (empty($this->input->post("birds"))){ $birds= 0;
}
$qtt= $this->input->post("qtt");
if (empty($this->input->post("qtt"))){ $qtt= 0;
}
$red= $this->input->post("red");
if (empty($this->input->post("red"))){ $red= 0;
}
$blue= $this->input->post("blue");
if (empty($this->input->post("blue"))){ $blue= 0;
}
$grey= $this->input->post("grey");
if (empty($this->input->post("grey"))){ $grey= 0;
}
$yellow= $this->input->post("yellow");
if (empty($this->input->post("yellow"))){ $yellow= 0;
}
$dark= $this->input->post("dark");
if (empty($this->input->post("dark"))){ $dark= 0;
}
for($x = 0; $x < sizeof($birds); $x++){
$reslt[$x] = array(
"birds" => $birds[$x],
"qtt" => $qtt[$x],
"red" => $red[$x],
"blue" => $blue[$x],
"grey" => $grey[$x],
"yellow" => $yellow[$x],
"dark" => $dark[$x]
);
}
$this->db->update_batch('db_birds', $reslt, 'birds');
dopo aver eseguito quel codice, php ha un errore come questo:
A PHP Error was encountered

Grazie cordiali saluti

Codice controller: -
for($x = 0; $x < sizeof($birds); $x++){
$reslt[$x] = array(
"birds" => $birds[$x],
"qtt" => $qtt[$x],
"red" => $red[$x],
"blue" => $blue[$x],
"grey" => $grey[$x],
"yellow" => $yellow[$x],
"dark" => $dark[$x]
);
}
$this->db->update_batch('db_birds', $reslt, 'birds');
La modifica è nel codice di visualizzazione: -
<?php
//sql Query.
//execute Query.
$ii=0; foreach($dps as $dp){ $iii = $ii++; <tr> <td><input type="hidden" name="birds[<?php echo $iii;?>]" value='<?php echo $dp['birds']; ?>' /><?php echo $dp['birds']; ?></td>
<td><p align='center'><input type="text" name="qtt[]" value='<?php echo $dp['qtt']; ?>' tabindex="2" style="width:30px;" /></td> <td><p align='center'><input type="checkbox" name="red[<?php echo $iii;?>]" value='1' <?php if($dp['red']==1) { echo " checked=\"checked\""; } ?> /></td> <td><p align='center'><input type="checkbox" name="blue[<?php echo $iii;?>]" value='1' <?php if($dp['blue']==1) { echo " checked=\"checked\""; } ?> /></td> <td><p align='center'><input type="checkbox" name="grey[<?php echo $iii;?>]" value='1' <?php if($dp['grey']==1) { echo " checked=\"checked\""; } ?> /></td> <td><p align='center'><input type="checkbox" name="yellow[<?php echo $iii;?>]" value='1' <?php if($dp['yellow']==1) { echo " checked=\"checked\""; } ?> /></td> <td><p align='center'><input type="checkbox" name="dark[<?php echo $iii;?>]" value='1' <?php if($dp['dark']==1) { echo " checked=\"checked\""; } ?> /></td>
</tr>
}
