解决方案
这是您的答案，它会选择您的最后选择下拉状态......
从选项中删除id < option id =emp ，或使用唯一的ID。
< select name =attendance-listid =attendance-listclass =形式控制>
<？php
$ save_drop_down_value = $ this-> input-> post（'attendance-list''）;
//根据您的项目更改此行..
foreach（$ attendance_dropdown as $ value）{
$ select =;
if（$ save_drop_down_value == $ value ['emp_id']）{
$ select =selected;
}
？>
< option<？php echo $ select;？> value = <？php echo $ value ['emp_id'];？>>
<？php echo $ value ['emp_name'];？>
< / option>
<？php}？>
I want to set the value to selected that has been selected in dropdown list and also want to print that value that has been submitted in that form.
When i print print_r[$value]; i just get some values.
Below is my code:
<form method="post" action="" id="date_date" name="date_data">
<div class="col-sm-4">
<h3><label for="sel1">Select From Date:</label></h3>
<h3><?php echo $this->input->post('date_data');?></h3>
<input type="text" id="datepicker" name="date_data">
</div>
<div class="col-sm-4">
<h3><label for="sel1">Select To Date:</label></h3>
<h3><?php echo $this->input->post('to_data');?></h3>
<input type="text" id="datepicker_to" name="to_data">
</div>
<div class="col-sm-4">
<?php
$user_type = $this->session->userdata('user_type');
if($user_type =="admin")
{
?>
<div class="form-group">
<h3><label for="sel1">Select Employoee Name:</label></h3>
<select name="attendance-list" id="attendance-list" class="form-control" >
<?php foreach($attendance_dropdown as $value)
{
?>
<option id="emp" value="<?php echo $value['emp_id'];?>"><?php echo $value['emp_name'];?></option>
$dropdown = str_replace("value='".$rid."'","value='".$rid."' selected=\"selected\"",$dropdown);
<?php
}
?>
</select>
<?php echo "<br>"; ?>
</div>
<?php
}
else
{
?>
<div class="form-group">
<input type="hidden" name="attendance-list" value="<?php echo $this->session->userdata('emp_id'); ?>">
</div>
<?php
}
?>
</div> <!--Col-sm-8-->
<div class="col-sm-4">
<h3><label for="sel1"></label></h3>
<input type="submit" value="submit" class="btn btn-primary">
</div>
</form>
解决方案
Here is your answer, it will select your last select dropdown state...
Remove id from option <option id="emp" use class if you want, or use unique id.
<select name="attendance-list" id="attendance-list" class="form-control" >
<?php
$save_drop_down_value = $this->input->post('attendance-list"');
//change this line according to your project..
foreach($attendance_dropdown as $value) {
$select = "";
if( $save_drop_down_value == $value['emp_id']){
$select = "selected";
}
?>
<option <?php echo $select; ?> value="<?php echo $value['emp_id'];?>">
<?php echo $value['emp_name'];?>
</option>
<?php } ?>
