I want to send the value from this form to the same page, but the submit button not send the value
This is the form:
<form method="post" action="">
<select name="b" value="<?=isset($_POST['b']) ? CHtml::encode($_POST['b']) : '' ; ?>">
<option value="1">Januari</option>
<option value="2">Februari</option>
<option value="3">Mac</option>
<option value="4">April</option>
<option value="5">Mei</option>
<option value="6">Jun</option>
<option value="7">Julai</option>
<option value="8">Ogos</option>
<option value="9">September</option>
<option value="10">Oktober</option>
<option value="11">November</option>
<option value="12">Disember</option>
</select>
<input type="submit" value="Papar Statistik" /><hr />
</form>
This is the funtion that use to Get the data value from form above:
<?php
if (isset($_GET['b']) && !empty($_GET['b']))
$current_month = $_GET['b'];
else
$month = date('Y-m-d', time());
$bulan = strtotime($month); // FUNCTION CONVERSION DATE KEPADA DAY
$current_month = date("m", $bulan);
$teacher = Yii::app()->user->getId();
$jumlahStatistik_hadir = 0;
for ($d = 1; $d <= 30; $d++){
$statistik_hadir = Detail::model()->countByAttributes(array(
'status' => '1',
'date' => '2015-'.$current_month.'-'.$d.'',
'teacher_id' => $teacher));
$jumlahStatistik_hadir =
($jumlahStatistik_hadir+$statistik_hadir);
}
print_r ($jumlahStatistik_hadir);
?>
If you are sending your form data using POST method
<form method="post" action="">
<select name="b">
<option value="1">Januari</option>
<option value="2">Februari</option>
</select>
</form>
You can expect the PHP to provide the data in the $_POST global, not post.
// This is correct
echo $_POST['b'];
// This is not correct
echo $_GET['b'];
NOTE: Instead of using 'value' in your select tag.
<select name="b" value="2">
You need to provide the selected option for the chosen value
<option value="1">Januari</option>
<option value="2" selected='selected'>Februari</option>
