将删除按钮添加到显示mysql表内容的php代码中
[英]Adding delete button to php code displaying mysql table contents
问题描述
I have searched for an answer that relates to my code but I'm new to php and html so I would appreciate the help. 
我已经搜索了与我的代码相关的答案，但是我是php和html的新手，所以我将非常感谢您的帮助。
So I've created code that uses loops to display a html table with the contents of the specified table from a mysql database. 因此，我创建了使用循环从mysql数据库显示带有指定表内容的html表的代码。 I would like to give the user an option to delete a row when the results are displayed. 我想给用户一个选项，在显示结果时删除一行。
This is my code so far to display the results of my database table: 到目前为止，这是我的代码，用于显示数据库表的结果：
<html><head><title>MySQL Table Viewer</title></head><body>
<?php
$db_host = 'localhost';
$db_user = 'username';
$db_pwd = 'password';
$database = 'dvdproject';
$table = 'Employee';
$con= mysql_connect($db_host,$db_user,$db_pwd,$database);
if(!$con){
die("Can not connect" . mysql_error());
}
mysql_select_db($database,$con);
// sending query
$result = mysql_query("SELECT * FROM {$table}");
$fields_num = mysql_num_fields($result);
echo "<h1>Table: {$table}</h1>";
echo "<table border='1'><tr>";
// printing table headers
for($i=0; $i<$fields_num; $i++)
{
$field = mysql_fetch_field($result);
echo "<td>{$field->name}</td>";
}
echo "</tr>\n";
// printing table rows
while($row = mysql_fetch_row($result))
{
echo "<tr>";
foreach($row as $cell)
echo "<td>$cell</td>";
echo '<form method="POST" name="deleterequest" action =
"deleterequest.php">';
echo "<input name='record_id' type='hidden' value='".$row['id']."'
>";
echo "<input name='delete'type='submit' value='Delete' >";
echo "</form>";
echo "</tr>\n";
}
echo "</table>";
mysql_close($con);
?>
No matter where I place my form to delete button, 6 delete buttons take up an entire row followed by the actual rows. 无论我将表单放置在哪里删除按钮，6个删除按钮都会占据整行，然后是实际行。 I would like the delete button to be after each row but I just cant get my head around it! 我希望删除按钮位于每一行之后，但我无法理解它！

Apologies if I am overlooking something here, but have you tried wrapping your delete button with <td> tags? 抱歉，如果我在这里忽略了某些内容，但是您是否尝试过使用<td>标签包装删除按钮？
foreach($row as $cell)
echo "<td>$cell</td>";
echo "<td>";
echo '<form method="POST" name="deleterequest" action="deleterequest.php">';
echo "<input name='record_id' type='hidden' value='".$row['id']."'>";
echo "<input name='delete'type='submit' value='Delete' >";
echo "</form>";
echo "</td>";
echo "</tr>\n";
}
I stripped everything bar HTML away from this and found a <td> tag around the form worked a treat. 我从中剥离了所有HTML内容，发现表单周围的<td>标签有效。
