Codeigniter aggiornamento batch per casella di controllo

Nov 02 2020

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

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>
  }
  
  
?>
