我正在CodeIgniter的網站上工作。我想檢查日期是否已經存在於數據庫中。我已經編寫所需的功能,但submiting形式時,我得到一個錯誤:檢查日期是否存在jQuery驗證器,ajax和CodeIgneter
POST 500 (Internal Server Error)
這裏是我的模型:
private function tanggal($date)
\t {
\t \t $this->db->where('start_date', $date);
\t \t $query = $this->db->get('t_trx_activity');
\t \t if($query->num_rows() > 0){ return TRUE; } else { return FALSE; }
\t }
我的控制器:
function validate_date()
\t {
\t if (array_key_exists('start',$_POST)) {
\t if ($this->activity->tanggal($this->input->post('start')) == TRUE) {
\t \t echo false;;
\t \t } else {
\t \t echo true;
\t \t }
\t \t }
\t }
我的觀點:
<form class="form-horizontal" id="form-date" role="form" method="post" action="<?php echo base_url(); ?>activity/add">
<div class="form-group">
<label class="col-sm-3 control-label">Start Date:<span
class="required">*</span> </label>
<div class="col-sm-7">
<div class="input-group date date-picker" data-date-format="yyyy-mm-dd">
<input type="text" class="form-control" readonly id="date" name="start" required>
<span class="input-group-addon">
<span class="glyphicon glyphicon-calendar"></span>
</span></div>
</div>
</div>
<div class="form-group">
<label class="col-sm-3 control-label">End Date:<span
class="required">*</span> </label>
<div class="col-sm-7">
<div class="input-group date date-picker" data-date-format="yyyy-mm-dd">
<input type="text" class="form-control" readonly name="end" required>
<span class="input-group-addon">
<span class="glyphicon glyphicon-calendar"></span>
</span></div>
</div>
</div>
<button type="submit" class="btn green">
<i class="fa fa-pencil"></i> Create</button>
jQuery驗證:
var FormValidation = function() {
var handleValidation = function() {
var form = $('#form-date');
var error = $('.alert-danger', form);
var success = $('.alert-success', form);
form.validate({
errorElement: 'span', //default input error message container
errorClass: 'help-block help-block-error', // default input error message class
focusInvalid: false, // do not focus the last invalid input
ignore: "", // validate all fields including form hidden input
rules: {
start: {
required: true,
date: true,
remote: {
url: "<?php echo site_url('activity/validate_date')?>",
type: "post",
data: {
date: function(){ return $("#date").val(); }
}
}
},
end: {
required: true
},
},
messages: {
start:
{
remote: 'Date already in use.'
}
},
這個豪任何想法這可以解決嗎?
maby'echo false ;;'是問題,打開路線在一個新的頁面,看看是否它有任何錯誤 – madalinivascu
有任何PHP錯誤日誌? –
您的模型函數'tanggal'必須是'public'而不是'private' –
