[英]CodeIgniter: form submitted with <enter> fails form validation
I have this problem with CodeIgniter: - when I click the submit button in a form, the form is submitted and validated correctly - when I don't click the submit button, just hit <enter>
, the form validation always fails Any solution? 我有CodeIgniter的这个问题: - 当我单击表单中的提交按钮时,表单被正确提交和验证 - 当我没有单击提交按钮时,只需点击<enter>
,表单验证总是失败任何解决方案? Is that a flaw in CI's form validation or am I missing something? 这是CI表单验证中的缺陷还是我遗漏了一些东西?
What code I have there: 那里有什么代码:
--- the form view ---
form_open("/");
...some inputs...
echo form_submit('submit', 'Přihlásit');
form_close();
...
--- the controller ---
$this->CI->load->helper('form');
$this->CI->load->library('form_validation');
$this->CI->form_validation->set_rules('id_uziv', 'ID', 'required');
$this->CI->form_validation->set_rules('heslo', 'Heslo', 'required');
//... see, no rules have anyhting to do with the submit button
if ($this->CI->form_validation->run() == FALSE) {
// validation OK
}
else {
// validation failed
}
you're not echoing form_open('/')
你没有回应form_open('/')
your form elements will not be enclosed within a <form>
element so when you submit, no post data will be sent to the server resulting in your validation failing. 您的表单元素不会包含在<form>
元素中,因此在您提交时,不会将任何发布数据发送到服务器,从而导致验证失败。
I solved it by adding an empty validation rule for the submit button, like this: 我通过为提交按钮添加一个空的验证规则来解决它,如下所示:
$this->CI->form_validation->set_rules('submit_button', 'Submit', '');
Now it works. 现在它有效。 I don't really know what was causing the problem. 我真的不知道是什么引起了问题。
