多个PHP表单函数

Question

我有些麻烦让一些HTML / PHP工作。我有一个包含3个基本表区域的HTML文件。在一个区域中，我有一个输入字段和一个与SQL数据库通信的按钮，用于删除HTML框中提供的条目。在第二个表格行中，我有一个表单，用于将新项目添加到数据库中。

然而，当我按下第二个表区域中的按钮时，它会运行第一个PHP函数。我错过了什么吗？

<table width="651" height="231" border="1">
  <tr>
  <td width="1163" height="23">&nbsp;</td>
</tr>
<tr>
<td height="96">
<table>
<form method=post action="removeRecord.php">
<input type="text" name="boatNumber" font color="white"> Enter a boat to remove<br>
<input type=submit value="Remove boat">
</table>
</td>
</tr>
<tr>
<td height="102">
<h1>Register a new boat.</h1>
<table>
<form method=post action="addRecord.php">
<input type="text" name="boatNumberNew" font color="white"> Enter the boats number.<br>
<input type="text" name="boatType" font color="white"> Enter the type of boat.<br>
<input type="text" name="decks" font color="white"> :Number of Decks<br>
<input type="text" name="cabins" font color="white"> :Number of cabins<br>
<input type="text" name="location" font color="white"> Location.<br>
<input type="text" name="rent" font color="white"> Rent.<br>
<input type="text" name="staffNumber" font color="white"> Enter assigned staff member.<br>
<input type="text" name="branchNumber" font color="white"> Enter assigned branch.<br>
<input type="text" name="ownerNumber" font color="white"> Enter owner number.<br>
<input type=submit value="Add boat">
</table>
</td>
</tr>
</table>

Answer 1

您错过了两个表单的结束</form>标记。

另外，引用type=submit和method=post

这是重写：

<table width="651" height="231" border="1">
  <tr>
  <td width="1163" height="23">&nbsp;</td>
</tr>
<tr>
<td height="96">
<table>
<form method="post" action="removeRecord.php">
<input type="text" name="boatNumber" font color="white"> Enter a boat to remove<br>
<input type="submit" value="Remove boat">
</form>
</table>
</td>
</tr>
<tr>
<td height="102">
<h1>Register a new boat.</h1>
<table>
<form method="post" action="addRecord.php">
<input type="text" name="boatNumberNew" font color="white"> Enter the boats number.<br>
<input type="text" name="boatType" font color="white"> Enter the type of boat.<br>
<input type="text" name="decks" font color="white"> :Number of Decks<br>
<input type="text" name="cabins" font color="white"> :Number of cabins<br>
<input type="text" name="location" font color="white"> Location.<br>
<input type="text" name="rent" font color="white"> Rent.<br>
<input type="text" name="staffNumber" font color="white"> Enter assigned staff member.<br>
<input type="text" name="branchNumber" font color="white"> Enter assigned branch.<br>
<input type="text" name="ownerNumber" font color="white"> Enter owner number.<br>
<input type="submit" value="Add boat">
</form>
</table>
</td>
</tr>
</table>

应用Marc B的建议进行另一次改写：

<table width="651" height="231" border="1">
  <tr>
  <td width="1163" height="23">&nbsp;</td>
</tr>
<tr>
<td height="96">
<form method="post" action="removeRecord.php">
<table>

<input type="text" name="boatNumber" font color="white"> Enter a boat to remove<br>
<input type="submit" value="Remove boat">

</table>
</form>
</td>
</tr>
<tr>
<td height="102">
<h1>Register a new boat.</h1>
<form method="post" action="addRecord.php">
<table>

<input type="text" name="boatNumberNew" font color="white"> Enter the boats number.<br>
<input type="text" name="boatType" font color="white"> Enter the type of boat.<br>
<input type="text" name="decks" font color="white"> :Number of Decks<br>
<input type="text" name="cabins" font color="white"> :Number of cabins<br>
<input type="text" name="location" font color="white"> Location.<br>
<input type="text" name="rent" font color="white"> Rent.<br>
<input type="text" name="staffNumber" font color="white"> Enter assigned staff member.<br>
<input type="text" name="branchNumber" font color="white"> Enter assigned branch.<br>
<input type="text" name="ownerNumber" font color="white"> Enter owner number.<br>
<input type="submit" value="Add boat">

</table>
</form>
</td>
</tr>
</table>

Answer 2

您的HTML从根本上被打破了：

<table>
<form>...</form>
</table>

无效。 <table>只能有与表相关的子节点（tr，td，thead，tbody等）。表格应该在表格之外：

<form>
<table> ... </table>
</form>

另外，你永远不会关闭你打开的第一个表格，这意味着：

<form action="foo.php">
...
<form action="bar.php">  
<input type="submit">
</form>

将提交给foo.php，因为您无法将表单嵌套在彼此中。

Answer 3

您需要添加

<input type="hidden" name="action" value="youraction"/>告诉php执行哪种形式的php验证

第二，您缺少表单</form>

的结束标记

Answer 4

使用</form>关闭表单

</form>
