以下代码用于更新MySQL表中的数据。它是通过从一个查询中提取所有数据来编写的,但我尝试调整它以从两个查询中提取数据以改进排序。现在只有部分记录在点击提交按钮时更新,我不确定如何修复它。
原始代码是:
if(isset($_POST['submit'])){
$password = $_POST['password'];
$total = $_POST['total'];
$park_id = $_POST['park_id'];
if($password=="****"){
for($i =1; $i<=$total; $i++){
$ride_id = $_POST['ride_id'.$i];
$name = $_POST['ride_name'.$i];
$type = $_POST['type'.$i];
$topride = $_POST['topride'.$i];
$info = $_POST['info'.$i];
$speed = $_POST['speed'.$i];
$height = $_POST['height'.$i];
$length = $_POST['length'.$i];
$inversions = $_POST['inversions'.$i];
$query = "update tpf_rides set name='$name',type='$type'";
if($topride!=""){$query .= ",top_ride=$topride";}
if($info!=""){$query .= ",info='$info'";}
if($height!=""){$query .= ",height=$height";}
if($length!=""){$query .= ",length=$length";}
if($speed!=""){$query .= ",speed=$speed";}
if($inversions!=""){$query .= ",inversions=$inversions";}
$query .= " where ride_id=".$ride_id." and park_id=".$park_id;
mysql_query($query);
}
header('location:index.php?msg=Successfully Updated.');
}else{
echo "Enter Correct Password.";
}
}
if(isset($_GET['id'])){
$id = $_GET['id'];
$sql = "select name from tpf_parks where park_id=".$id;
$result = mysql_fetch_array(mysql_query($sql));
echo '<h2>'.$result['name'].'</h2>';
$qry = "select * from tpf_rides where park_id=".$id;
$res = mysql_query($qry);
$no = mysql_num_rows($res);
$x = 0;
if($no>0){ ?>
<form action="" method="post">
<input type="hidden" value="<?=$no?>" name="total">
<input type="hidden" value="<?=$id?>" name="park_id">
<table> <?php
while($row = mysql_fetch_array($res)){ $x++;
echo '<input type="hidden" value="'.$row['ride_id'].'" name="ride_id'.$x.'">';
echo '<tr><td>Name : </td><td><input type="text" name="ride_name'.$x.'" value="'.$row['name'].'"></td></tr>';
echo '<tr><td>Type : </td><td><input type="text" name="type'.$x.'" value="'.$row['type'].'"></td></tr>';
echo '<tr><td>Top Ride : </td><td><input type="text" name="topride'.$x.'" value="'.$row['top_ride'].'"></td></tr>';
echo '<tr><td>Info : </td><td><input type="text" name="info'.$x.'" value="'.$row['info'].'"></td></tr>';
if($row['type']!="Roller Coaster"){
echo '<tr><td>Speed : </td><td><input type="text" name="speed'.$x.'" value="'.$row['speed'].'"></td></tr>';
echo '<tr><td>Height : </td><td><input type="text" name="height'.$x.'" value="'.$row['height'].'"></td></tr>';
echo '<tr><td>Length : </td><td><input type="text" name="length'.$x.'" value="'.$row['length'].'"></td></tr>';
echo '<tr><td>Inversions : </td><td><input type="text" name="inversions'.$x.'" value="'.$row['inversions'].'"></td></tr>';
}
echo '<tr><td colspan="2"><hr></td></tr>';
} ?>
<tr><td>Password :</td><td><input type="password" value="" name="password" id="password"></td></tr>
<tr><td></td><td><input onclick="return check()" type="submit" value="Save" name="submit"></td></tr>
</table>
</form>
<?php
}else{
echo "No Rides in this park.";
}
}else{
if(isset($_GET['msg'])){echo $_GET['msg'].'<br>';}
$qry = "select * from tpf_parks order by name";
$res = mysql_query($qry);
?>
Select Park : <select name="park" onChange="getdata(this.options[this.selectedIndex].value)">
<option value="">Select Park</option>
<?php
while($row = mysql_fetch_array($res)) { ?>
<option value="<?=$row['park_id']?>"><?=$row['name']?></option>
<? } ?>
</select>
<?php } ?>
和我改变查询的新代码在这里:
if(isset($_POST['submit'])){
$password = $_POST['password'];
$total = $_POST['total'];
$park_id = $_POST['park_id'];
if($password=="*****"){
for($i =1; $i<=$total; $i++){
$ride_id = $_POST['ride_id'.$i];
$name = $_POST['ride_name'.$i];
$type = $_POST['type'.$i];
$topride = $_POST['topride'.$i];
$info = $_POST['info'.$i];
$speed = $_POST['speed'.$i];
$height = $_POST['height'.$i];
$length = $_POST['length'.$i];
$inversions = $_POST['inversions'.$i];
$query = "update tpf_rides set name='$name',type='$type'";
if($topride!=""){$query .= ",top_ride=$topride";}
$query .= ",info='$info'";
if($height!=""){$query .= ",height=$height";}
if($length!=""){$query .= ",length=$length";}
if($speed!=""){$query .= ",speed=$speed";}
if($inversions!=""){$query .= ",inversions=$inversions";}
$query .= " where ride_id=".$ride_id." and park_id=".$park_id;
mysql_query($query);
}
header('location:index.php?msg=Successfully Updated.');
}else{
echo "Enter Correct Password.";
}
}
if(isset($_GET['id'])){
$id = $_GET['id'];
$sql = "select name from tpf_parks where park_id=".$id;
$result = mysql_fetch_array(mysql_query($sql));
echo '<h2>'.$result['name'].'</h2>';
$qry = "SELECT * FROM tpf_rides
WHERE park_id = $id AND type LIKE '%Roller Coaster%' ORDER BY name ASC";
$res = mysql_query($qry);
$qry2 = "SELECT * FROM tpf_rides
WHERE park_id = $id AND type NOT LIKE '%Roller Coaster%' ORDER BY name ASC";
$res2 = mysql_query($qry2);
$qry3 = "SELECT * FROM tpf_rides WHERE park_id = $id";
$res3 = mysql_query($qry2);
$no = mysql_num_rows($res3);
$x = 0;
$xx = 0;
if($no>0){ ?>
<form action="" method="post">
<input type="hidden" value="<?=$no?>" name="total">

</table>
</form>
<?php

echo "No Rides in this park.";
}
}else{
if(isset($_GET['msg'])){echo $_GET['msg'].'<br>';}
$qry = "select * from tpf_parks order by name";
$res = mysql_query($qry);

在测试未修改的内容之后,是否跳过LIKE和NOT LIKE查询的数据,这可能是记录计数问题? 我做错了什么想法?
答案 0 :(得分:0)
您确定您的列类型是否具有“过山车”的价值?
很抱歉发帖作为答案,因为我没有权利没有评论。
