Question

我是cakephp的新手，我正在尝试为程序名称进行数据验证。我希望我的程序名称只允许使用alphaNumeric或字符。我不希望它允许仅数字或特殊字符。实际上，由于第二条规则，不允许使用Numeric或alphaNumeric。这是我的代码

$validate = array(    
    'program_name' => array(
        'required' => array(
            'rule' => 'isUnique',
            'allowEmpty'=> false,
            'message' => 'This Program Name already exists. Please enter a Program Name'
        ),
        'alphaNumeric'=> array(
            'rule' => 'alphaNumeric',
            'message'=> 'Please enter a valid name'
        ),
        'name' => array(
            'rule'    => '/^[a-zA-Z]*$/',
            'message' => 'Only letters or alphaNumerics. Please enter a valid name')
        )
    )
    //Validation rules for other fields, if any
);

您对“必需”的使用已关闭，可能应该是这样：

$validate = array(    
    'program_name' => array(
        'isUnique' => array(
            'rule' => 'isUnique',
            'allowEmpty'=> false,
            'required' => true,
            'message' => 'This Program Name already exists. Please enter a Program Name'
        ),
        'alphaNumeric'=> array(
            'rule' => 'alphaNumeric',
            'message'=> 'Please enter a valid name'
        ),
        'name' => array(
            'rule'    => '/^[a-zA-Z]*$/',
            'message' => 'Only letters or alphaNumerics. Please enter a valid name')
        )
    )
    //Validation rules for other fields, if any
);

现在，在修复了“必需”的使用后，我们将继续讨论您的问题。如果要检查字符串是否包含alphaNumeric字符，而不仅仅是数字：您需要编辑“名称”规则中定义的正则表达式。我建议使用this question答案中的正则表达式。所以：用我提到的帖子中的正则表达式替换/^[a-zA-Z]*$/，然后删除名为alphaNumeric的规则，所以你的代码如下所示：

$validate = array(    
    'program_name' => array(
        'isUnique' => array(
            'rule' => 'isUnique',
            'allowEmpty'=> false,
            'required' => true,
            'message' => 'This Program Name already exists. Please enter a Program Name'
        ),
        'name' => array(
            'rule'    => '/^(?![0-9]*$)[a-zA-Z0-9]+$/',
            'message' => 'Only letters or alphaNumerics. Please enter a valid name')
        )
    )
    //Validation rules for other fields, if any
);

数据验证不允许使用数字
