我想將一條消息保存在PHP變量中,並用已返回的其他數組變量發回。例如,我在PHP代碼中發生了一些錯誤檢查,並想要一個字符串變量,並將特定的消息發送回我的javascript中使用。將字符串變量從PHP發送回數組變量的ajax ...?
這裏是PHP:
<?php
include('config-searchres.php');
$term = $_POST['resid'];
$sql = mysql_query("SELECT * FROM ap_form_8 WHERE id = '$term'"); //select first name (element_1_1) from form #8
if ($row = mysql_fetch_array($sql)){ //if reservation number exists
if ($row['element_11'] != 'Cancelled'){ //if reservation has not already been cancelled
if (strtotime($row['element_3']) >= strtotime(date("Y-m-d"))){ //if reservation has not already passed date
echo json_encode($row);
}
else //Reservation already passed (old reservation)
{
echo 'passed';
}
}
else //Reservation already cancelled
{
echo 'cancelled';
}
}
else //Reservation not found
{
echo 'not found';
}
mysql_close();
?>
正如你可以看到,有3級不同的消息,「合格」,「取消」和「未找到」 ......如果這些條件之一存在,我想把這個字符串發回給我的JavaScript,所以我可以在DIV中顯示它。不過,我也想發送$ row數據。
我的javascript:
<script type="text/javascript">
$(document).ready(function(){
resetForms('reservation');
$('#form-reservation').submit(function(event){
event.preventDefault(); //the page will no longer refresh on form submit.
var resCheck = $(this).find('input[class="reservationid"]').val(); //now we have the reservation ID, let's perform our check.
$.ajax({
url: 'inc/searchres.php',
type: 'POST',
data: 'resid='+resCheck,
success: function(data){ //data is all the info being returned from the php file
$('#reservation-id').val(resCheck); //add read ID back into text box
var jsonData = $.parseJSON(data); //parse returned JSON data so we can use it like data.name, data.whatever
//****I wanted the line just below this to display the appropriate message sent back from the PHP****
$("#res-message").html('<a>Reservation ID Located, Information is displayed below</a>');
$('#json-reservation').populate({personal_first_name:jsonData['element_1_1'],personal_last_name:jsonData['element_1_2'],personal_phone_1:jsonData['element_7'],personal_email:jsonData['element_2'],reservation_status:jsonData['ADD THIS CELL'], reservation_id:jsonData['id'], reservation_date:jsonData['element_3'],reservation_time:jsonData['element_4'],reservation_party:jsonData['element_5'],reservation_special_request:jsonData['element_6'],reservation_using_coupon:jsonData['element_9'],reservation_coupon_code:jsonData['element_10'],reservation_status:jsonData['element_11']});
$("#res-cancel-message").html('');
},
error: function(){
$("#res-message").html('<a>There was an error with your request</a>');
$("#res-cancel-message").html('');
}
});
});
});
</script>
我打上,我填充在這個時候一個靜態的消息DIV星號,這是我會填充從PHP消息的線。有任何想法嗎?
我如何在JS中拆分它們?目前我設置數據數組爲:var jsonData = $ .parseJSON(data);由於消息和數據現在都存儲在這個數組中,我將如何將它們分開? – tmparisi 2012-04-26 17:32:05
nm,我可以通過jsonData.status或.data訪問.....謝謝! – tmparisi 2012-04-26 21:38:32
