我有一些像这样的PHP代码:
$row = mysql_fetch_array ( mysql_query("SELECT * FROM `tblFacilityHrs` WHERE `uid` = '$uid'"));
我现在正尝试将其转换为mysqli_fetch_array
,如此处所示http://php.net/manual/en/mysqli-result.fetch-array.php(示例#1面向对象的样式)
我不确定这个例子的意思是" $ result"。
这是我到目前为止转换代码的原因:
<?php
include('../config.php');
if (isset($_GET['uid']) ) {
$uid = $_GET['uid'];
$id = $_GET['id'];
if (isset($_POST['submitted'])) {
foreach($_POST AS $key => $value) { $_POST[$key] = mysqli_real_escape_string($value); }
//Query for tblFacilityHrs
$sql = " UPDATE tblFacilityHrs SET `title`='{$_POST['title']}',`description`='{$_POST['description']}' WHERE `uid` = '$uid' ";
$result = $mysqli->query($sql) or die($mysqli->error);
//Query for tblFacilityHrsDateTimes
$sql2 = "UPDATE tblFacilityHrsDateTimes SET `startEventDate`='{$_POST['startEventDate']}',`endEventDate`='{$_POST['endEventDate']}', `startTime`='{$_POST['startTime']}',`endTime`='{$_POST['endTime']}',`days`='{$_POST['days']}',`recurrence`='{$_POST['recurrence']},`finalDate`='{$_POST['finalDate']}' WHERE `id` = '$id' "; print $sql2;
$result2 = $mysqli->query($sql2) or die($mysqli->error);
echo ($mysqli->affected_rows) ? "Edited row.<br />" : "Nothing changed. <br />";
echo "<a href='list.php'>Back</a>";
}
$row = $result->fetch_array($mysqli->query("SELECT * FROM `tblFacilityHrs` WHERE `uid` = '$uid'"));
$row2 = $result2->fetch_array($mysqli->query("SELECT * FROM `tblFacilityHrsDateTimes` WHERE `id` = '$id'"));
?>
因为我正在学习mysqli,所以可能有很多错误,但现在它在
上出错了致命错误:调用成员函数fetch_array()

UPDATE
查询不返回结果对象,它返回TRUE
(假设成功)。您接着尝试拨打TRUE->fetch_array()
,这显然无效。
现在,为了做你真正想做的事,试试这个:
$row = $mysqli->query("SELECT.....")->fetch_array();
答案 1 :(得分:1)
看起来您正在尝试使用旧的结果对象(UPDATE的结果)来获取新查询的结果。您需要先运行新查询,将其结果分配给对象,然后从对象中获取结果。查看重写脚本的最后三行:
$facilityHoursQueryResult = $mysqli->query("SELECT * FROM `tblFacilityHrs` WHERE `uid` = '$uid'");
$facilityHoursDateTimesQueryResult = $mysqli->query("SELECT * FROM `tblFacilityHrsDateTimes` WHERE `id` = '$id'");
$facilityHoursRow = $facilityHoursQueryResult == FALSE ? NULL : $facilityHoursQueryResult->fetch_array();
$facilityDateTimesRow = $facilityHoursDateTimesQueryResult == FALSE ? NULL : $facilityHoursDateTimesQueryResult->fetch_array();
?>
这是一个包含其他结果对象方法的有用页面: http://www.php.net/manual/en/class.mysqli-result.php
