Question

我在添加视图中有这些代码

$status = array('0' => 'Resolved', '1' => 'Assigned/Unresolved', '2' => 'Suspended', '3' => 'Closed', '4' => 'Bypassed');
echo $this->Form->input('status', array('options' => $status));

而不是将值（例如Resolved）保存到表中，它保存了数组的索引。有什么想法吗？

Answer 1

你应该这样做：

$status = array('resolved' => 'Resolved', 'assigned' => 'Assigned/Unresolved'...);

它保存了数组的索引。但这不是一个好习惯，而是尝试使用枚举。看看这个：

/**
     * Get Enum Values
     * Snippet v0.1.3
     * http://cakeforge.org/snippet/detail.php?type=snippet&id=112
     *
     * Gets the enum values for MySQL 4 and 5 to use in selectTag()
     */
    function getEnumValues($columnName=null, $respectDefault=false)
    {
        if ($columnName==null) { return array(); } //no field specified
        //Get the name of the table
        $db =& ConnectionManager::getDataSource($this->useDbConfig);
        $tableName = $db->fullTableName($this, false);


        //Get the values for the specified column (database and version specific, needs testing)
        $result = $this->query("SHOW COLUMNS FROM {$tableName} LIKE '{$columnName}'");

        //figure out where in the result our Types are (this varies between mysql versions)
        $types = null;
        if     ( isset( $result[0]['COLUMNS']['Type'] ) ) { $types = $result[0]['COLUMNS']['Type']; $default = $result[0]['COLUMNS']['Default']; } //MySQL 5
        elseif ( isset( $result[0][0]['Type'] ) )         { $types = $result[0][0]['Type']; $default = $result[0][0]['Default']; } //MySQL 4
        else   { return array(); } //types return not accounted for

        //Get the values
        $values = explode("','", preg_replace("/(enum)\('(.+?)'\)/","\\2", $types) );

        if($respectDefault){
                    $assoc_values = array("$default"=>Inflector::humanize($default));
                    foreach ( $values as $value ) {
                                    if($value==$default){ continue; }
                                    $assoc_values[$value] = Inflector::humanize($value);
                    }
        }
        else{
                    $assoc_values = array();
                    foreach ( $values as $value ) {
                                    $assoc_values[$value] = Inflector::humanize($value);
                    }
        }

        return $assoc_values;
    } //end getEnumValues

将该方法粘贴到AppModel中。

在表中创建具有posible值的枚举列，并使用该方法获取它们。

您能否将索引定义为您想要的值？

$status = array('Resolved' => 'Resolved', 'Assigned/Unresolved' => 'Assigned/Unresolved', etc etc );
    echo $this->Form->input('status', array('options' => $status));

如何将数组的值保存到表中？
