我遇到的主要问题基本上就是:
我有一个while循环,可以从查询中生成结果。根据已生成的结果,我希望能够更新原始查询所来自的表。
查询产生预期结果,但单击REMOVE按钮时表未更新。我也试图找到一个解决方案,以便在UPDATE查询执行后更新结果...
<?php
$sql = "SELECT * FROM vehicles WHERE sold='n' ORDER BY year DESC";
$query = mysql_query($sql);
while ($row = mysql_fetch_array($query)) {
echo
"
<tr>
<td style='border-bottom-style:dotted;padding-top:10px;padding-bottom:10px;font-size:.9em'>",$row['year'],"</td>
<td style='border-bottom-style:dotted;padding-top:10px;padding-bottom:10px;font-size:.9em'>",$row['make'],"</td>
<td style='border-bottom-style:dotted;padding-top:10px;padding-bottom:10px;font-size:.9em'>",$row['model'],"</td>
<td style='border-bottom-style:dotted;padding-top:10px;padding-bottom:10px;font-size:.9em'><input type='submit' name='remove' value='REMOVE' style='background-color:#C33;color:white;padding:10px;border-radius:5px;width:70px'/></td>
</tr>";
if(isset($_POST['remove'])){
$removeSql = "UPDATE `table`.`vehicles` SET `display`='0' WHERE `vin`='{$row['vin']}'";
mysql_query($removeSql) or die('check that code dummy');
}
}
mysql_close($connection);
?>
答案 0 :(得分:0)
这是一个提交按钮,没有表单标签就行不通。你不能这样做。
您可以在单独的页面上撰写remove code
并将submit button
转换为normal button
并在vin id
click
上传递button
和使用call
的页面ajax
。
或者,如果您不知道ajax
并希望在该页面上执行此操作,请按以下方式执行:
<?php
$sql = "SELECT * FROM vehicles WHERE sold='n' ORDER BY year DESC";
$query = mysql_query($sql);
while ($row = mysql_fetch_array($query)) {
echo
"
<tr>
<td style='border-bottom-style:dotted;padding-top:10px;padding-bottom:10px;font-size:.9em'>",$row['year'],"</td>
<td style='border-bottom-style:dotted;padding-top:10px;padding-bottom:10px;font-size:.9em'>",$row['make'],"</td>
<td style='border-bottom-style:dotted;padding-top:10px;padding-bottom:10px;font-size:.9em'>",$row['model'],"</td>
<td style='border-bottom-style:dotted;padding-top:10px;padding-bottom:10px;font-size:.9em'>
<form action="" method="POST">
<input type="hidden" name="vin_id" value="<?php echo $row['vin']; ?>">
<input type='submit' name='remove' value='REMOVE' style='background-color:#C33;color:white;padding:10px;border-radius:5px;width:70px'/>
</form></td>
</tr>";
}
if(isset($_POST['remove'])){
$removeSql = "UPDATE `table`.`vehicles` SET `display`='0' WHERE `vin`='".$_POST['vin_id']."'";
mysql_query($removeSql) or die('check that code dummy');
}
mysql_close($connection);
?>
