(Resolvido) Manter Checkbox marcada ao submeter formulário com get

dinohills · June 30, 2011

Boa tarde !!

Estou montando uma tabela onde cada linha possuí uma checkbox, e ao submeter o formulário gostaria de manter as checkbox que o usuário selecionou marcadas para não precisar ficar remarcando toda vez que o formulário for submetido.

Mas o que acontece é o seguinte. Se eu marco apenas uma checkbox e envio o formulário essa checkbox não fica marcada, mas se eu marcar duas checkbox todas as checkbox ficam marcadas depois de submeter o fomulário.

Montei este exemplo simples do que eu estou tendo dificuldades.

<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title></title>
    </head>
    <body>
        <?php
        foreach ($_GET['box'] as $check => $valor) {            
            if ($check) {
                $marcado = "checked";
            }else{
                $marcado = "";
            }
        }
        ?>
        <form action="" method="get">
            <table border="1" width="300" align="center">
                <thead>
                <th>&nbsp;</th>
                <th>Item - A</th>
                <th>Item - B</th>
                </thead>
                <tbody align="center">
                    <tr>
                        <td><input type="checkbox" name="box[]" value="1" <?php echo $marcado; ?> </td>
                        <td>Item - 1</td>
                        <td>Item - 1</td>
                    </tr>
                    <tr>
                        <td><input type="checkbox" name="box[]" value="2" <?php echo $marcado; ?> </td>
                        <td>Item - 2</td>
                        <td>Item - 2</td>
                    </tr>
                    <tr>
                        <td><input type="checkbox" name="box[]" value="3" <?php echo $marcado; ?> </td>
                        <td>Item - 3</td>
                        <td>Item - 3</td>
                    </tr>
                    <tr>
                        <td><input type="checkbox" name="box[]" value="4" <?php echo $marcado; ?> </td>
                        <td>Item - 4</td>
                        <td>Item - 4</td>
                    </tr>
                    <tr>
                        <td><input type="checkbox" name="box[]" value="5" <?php echo $marcado; ?> </td>
                        <td>Item - 5</td>
                        <td>Item - 5</td>
                    </tr>
                </tbody>
                <tfoot>
                    <tr>
                        <td align="center" colspan="3"><input type="submit" value="envia"/></td>
                    </tr>
                </tfoot>
            </table>
        </form>        
    </body>
</html>

Acho que não falta muita coisa pra acertar !!

Bom se alguém tiver uma solução ou ideia qualquer coisa pra ajudar agradeço :D

Obrigado.

Consegui ajuda em outro forum, usando este código.

<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title></title>
    </head>
    <body>
        <form action="" method="POST">
            <table border="1" width="300" align="center">
                <thead>
                <th>&nbsp;</th>
                <th>Item - A</th>
                <th>Item - B</th>
                </thead>
                <tbody align="center">
                    <?php
                    $tableCells = array(
                        array('Item 1', 'Item 2'),
                        array('Item 1', 'Item 2'),
                        array('Item 1', 'Item 2'),
                        array('Item 1', 'Item 2'),
                        array('Item 1', 'Item 2'),
                    );
                    $i = 0;
                    foreach ( $tableCells as $cell ): ?>
                            <tr>
                                <td>
                                        <input
                                                type="checkbox"
                                                name="box[<?php echo $i; ?>]"
                                                value="1"
                                                <?php if ( isset( $_POST['box'][$i++] ) ) echo 'checked="checked"'; ?>
                                        />
                                </td>
                                <?php foreach ( $cell as $value ): ?>
                                        <td><?php echo $value; ?></td>
                                <?php endforeach; ?>
                            </tr>
                    <?php endforeach; ?>
                </tbody>
                <tfoot>
                    <tr>
                        <td align="center" colspan="3"><input type="submit" value="envia"/></td>
                    </tr>
                </tfoot>
            </table>
        </form>        
    </body>
</html>
