数组不是从HTML发送到PHP(Array not being sent from HTML to PHP)

我正在开展一个个人项目，让我可以记录我走过的所有苏格兰山脉（Munros）。我经常步行两次，每天3次，所以我需要一个动态的表格来控制有多少个字段。

我计划以4个数组存储关于山的数据，名称，高度，位置和最近的城镇。

当我将数据输入到表单中后，我点击提交并尝试在屏幕上显示名称以检查表单是否正常工作。

我似乎无法让阵列工作，虽然我确实有其他元素成功显示（例如加息的日期）。

下面是html

<form name="munroForm" action="process.php" class="register" method="POST"> <h1>Munro Data Entry Form</h1> <fieldset class="row1"> <legend>Trip Date</legend> <p> <label>Date of Trip*</label> <input type="date" required name="date"> </P> </fieldset> <fieldset class="row1"> <legend>Munro Details</legend> <table id="munroTable" class="form" border="1"> <tbody> <tr> <td><input type="checkbox" required="required" name="chk[]" checked="checked" /></td> <td> <label>Name *</label> <input type="text" maxlength = "30" required="required" name="name[]"> </td> <td> <label>Height *</label> <input type="text" maxlength = "5" required="required" name="height[]"> </td> <td> <label>Location</label> <input type="text" maxlength = "20" name="location[]"> </td> <td> <label>Closest Town</label> <input type="text" maxlength = "15" name="closest_town[]"> </td> </tr> </tbody> </table> <p> <input type="button" value="Add Munro" onClick="addRow('munroTable')" /> <input type="button" value="Remove Munro" onClick="deleteRow('munroTable')" /> </p> <div class="clear"></div> </fieldset> <input class="submit" type="submit" value="send" />

例如，我尝试了各种不同的php命令来尝试显示输入的数据

foreach ($_POST['name'] as $value) { // Do something with each valid friend entry ... if ($value) { echo $value."<br />"; } }

我甚至试图显示数组的大小，看它是否存储了正确数量的数据。这总是返回0。

echo "Number of munros =".sizeof($name);

我不确定JavaScipt是否干扰了这一点，尽管我怀疑它。但只要我把它粘贴在下面。

这是我第一次编写PHP以外的一些小的自定义wordpress主题。我在Mac上使用MAMP。

任何建议，将不胜感激。

I am working on a personal project that will allow me to log all the Scottish Mountains (munros) I have walked. I often walk two, or 3 a day so I needed a dynamic form to control how many fields to have.

I planned to store the data about the mountains in 4 arrays, Name, Height, Location and Closest Town.

When I enter the data into the form, I then hit submit and try to display the names on the screen to check that the form is working correctly.

I can't seem to get the arrays working although I do have other elements being displayed successfully (the date of the hike for example).

Below is the html

<form name="munroForm" action="process.php" class="register" method="POST"> <h1>Munro Data Entry Form</h1> <fieldset class="row1"> <legend>Trip Date</legend> <p> <label>Date of Trip*</label> <input type="date" required name="date"> </P> </fieldset> <fieldset class="row1"> <legend>Munro Details</legend> <table id="munroTable" class="form" border="1"> <tbody> <tr> <td><input type="checkbox" required="required" name="chk[]" checked="checked" /></td> <td> <label>Name *</label> <input type="text" maxlength = "30" required="required" name="name[]"> </td> <td> <label>Height *</label> <input type="text" maxlength = "5" required="required" name="height[]"> </td> <td> <label>Location</label> <input type="text" maxlength = "20" name="location[]"> </td> <td> <label>Closest Town</label> <input type="text" maxlength = "15" name="closest_town[]"> </td> </tr> </tbody> </table> <p> <input type="button" value="Add Munro" onClick="addRow('munroTable')" /> <input type="button" value="Remove Munro" onClick="deleteRow('munroTable')" /> </p> <div class="clear"></div> </fieldset> <input class="submit" type="submit" value="send" />

I have tried various different php commands to try and display the data entered, for example

foreach ($_POST['name'] as $value) { // Do something with each valid friend entry ... if ($value) { echo $value."<br />"; } }

I have even attempted to display the size of the array to see if it stores the correct amount of data. This always returns 0.

echo "Number of munros =".sizeof($name);

I am unsure if the JavaScipt is interfering with this, although I doubt it. But just incase I have pasted it below.

This is my first time writing PHP outside of doing some small customisations to wordpress themes. I am using MAMP on mac.

Any suggestions would be appreciated.
