Re: [請益] php 迴圈宣告變數
感謝各位板友的幫忙， 這部份我已經解決了 ~~~
但....下面要取值進mysql又遇到問題 ~"~
$camquery1 = "UPDATE test SET cam1 = '$cam[1]' WHERE email = '$email'";
mysql_query($query1, $con)
or die('Error in query1');
$camquery2 = "UPDATE test SET cam2 = '$cam[2]' WHERE email = '$email'";
mysql_query($query2, $con)
or die('Error in query2');
$camquery3 = "UPDATE test SET cam3 = '$cam[3]' WHERE email = '$email'";
mysql_query($query3, $con)
or die('Error in query3');
$camquery4 = "UPDATE test SET cam4 = '$cam[4]' WHERE email = '$email'";
mysql_query($query4, $con)
or die('Error in query4');
$camquery5 = "UPDATE test SET cam5 = '$cam[5]' WHERE email = '$email'";
mysql_query($query5, $con)
我使用
$camquery = array();
......
...... (略)
for ($i = 1; $i < 13; $i++) {
$camquery[$i] = "UPDATE test SET 'cam$i' = {$cam[$i]} WHERE email = '$email'";
mysql_query($camquery[$i], $con)
or die('Error in query');
}
這樣寫會跑進Error in query ........實在不曉得哪邊的問題 只好又發問 冏...
呃 有懷疑是 陣列不能存字串 但不確定 Orz .....再一次謝謝
※ 引述《winnieboy (~砍掉重練~)》之銘言：
: 各位前輩好 由於之前剛學php 亂寫了宣告以下 程式 - -
: $cam1 = $_POST['cam1'];
: $cam2 = $_POST['cam2'];
: $cam3 = $_POST['cam3'];
: $cam4 = $_POST['cam4'];
: $cam5 = $_POST['cam5'];
: $cam6 = $_POST['cam6'];
: $cam7 = $_POST['cam7'];
: $cam8 = $_POST['cam8'];
: $cam9 = $_POST['cam9'];
: $cam10 = $_POST['cam10'];
: $cam11 = $_POST['cam11'];
: $cam12 = $_POST['cam12'];
: 後來覺得應該可以用迴圈下去跑，看起來比較少行 - -
: 改成這樣
: for ($i = 1; $i < 13; $i++) {
: $cam$i = $_POST['cam'.$i];
: }
: 但是這樣就沒辦法跑了 我想請問一下 是我哪邊寫錯了 困擾了好久~~
