php在文件之间发送表单数据

我是php和表单开发的新手,这就是我想要实现的目标:

首先,我有一个简单的表单只输入两个文本值:

Form1
<br>
<form action="gather.php" method="post">
    Catalog:
    <input type="text" name="folderName" maxlength="50">
    <br>
    File Name:
    <input type="text" name="fileName" maxlength="50">
    <br>
    <input type="submit" name="formSubmit" value="Submit">
</form>

现在我有了第二个名为gather.php的文件,在那里我得到了两行,并使用它们来计算目录中的文件等。

<?php
if(isset($_POST['formSubmit'])){
    $folderName = $_POST['folderName'];
    $fileName = $_POST['fileName'];
    $numberOfImages = count(glob($folderName . "/*.jpg"));
    for($i = 1; $i <= $numberOfImages; $i++){
        echo "<br><input type=\"text\" name=\"imie" . $i . "\"><br/>\n";
        echo "<img src=\"" . $folderName . "/0" . $i . ".jpg\" height=\"50px\" width=\"50px\"><br><br>\n";
    }


    echo "\n<br>" . $folderName . "<br>" . $fileName . "\n";
}

?>
<br>
Final form
<br>
<form action="build.php" method="post">
<input type="submit" name="finalSubmit" value="Submit">
</form>

这应该让我看看build.php文件,它看起来更像这样:

<?php
if(isset($_POST['finalSubmit'])){
    //loop and other stuff
    $temp = $_POST['imie1'];
    echo $temp;

}
?>

所以问题是,在这个最终文件中,我想获取放在gather.php文件中的文本字段中的所有数据。但是我在build.php上得到了未定义的索引错误,说$ _POST ['imie1']中没有任何内容。你能告诉我为什么吗? tehre是从第二个文件到第三个文件获取此数据的方法吗?

编辑:thx的答案,因为我只接受1和多个是相同的我选择最少代表的用户只是为了支持她:)

您需要在表单标记内添加输入,否则不会发送。

    <br>
    Final form
    <br>
    <form action="build.php" method="post">
    <?php
    if(isset($_POST['formSubmit'])){
        $folderName = $_POST['folderName'];
        $fileName = $_POST['fileName'];
        $numberOfImages = count(glob($folderName . "/*.jpg"));
        for($i = 1; $i <= $numberOfImages; $i++){
            echo "<br><input type=\"text\" name=\"imie" . $i . "\"><br/>\n";
            echo "<img src=\"" . $folderName . "/0" . $i . ".jpg\" height=\"50px\" width=\"50px\"><br><br>\n";
        }


        echo "\n<br>" . $folderName . "<br>" . $fileName . "\n";
    }

    ?>
    <input type="submit" name="finalSubmit" value="Submit">
    </form>

替换你的gather.php
<br>
Final form
<br>
<form action="build.php" method="post">
<?php
    if(isset($_POST['formSubmit'])){
        $folderName = $_POST['folderName'];
        $fileName = $_POST['fileName'];
        $numberOfImages = count(glob($folderName . "/*.jpg"));
        for($i = 1; $i <= $numberOfImages; $i++){
            echo "<br><input type=\"text\" name=\"imie" . $i . "\"><br/>\n";
            echo "<img src=\"" . $folderName . "/0" . $i . ".jpg\" height=\"50px\" width=\"50px\"><br><br>\n";
        }


        echo "\n<br>" . $folderName . "<br>" . $fileName . "\n";
    }

    ?>
<input type="submit" name="finalSubmit" value="Submit">
</form>

你回应了表单外的输入框,现在它可以正常工作

我认为第二个表单上的<form>需要位于文件的顶部 - 它只会在标记内部提交元素,因此您生成HTML然后打开表单,它就是没有提交。

<br> 
Final form 
<br> 
<form action="build.php" method="post"> 
<?php 
if(isset($_POST['formSubmit'])){ 
    $folderName = $_POST['folderName']; 
    $fileName = $_POST['fileName']; 
    $numberOfImages = count(glob($folderName . "/*.jpg")); 
    for($i = 1; $i <= $numberOfImages; $i++){ 
        echo "<br><input type=\"text\" name=\"imie" . $i . "\"><br/>\n"; 
        echo "<img src=\"" . $folderName . "/0" . $i . ".jpg\" height=\"50px\" width=\"50px\"><br><br>\n"; 
    } 


    echo "\n<br>" . $folderName . "<br>" . $fileName . "\n"; 
} 

?> 
<input type="submit" name="finalSubmit" value="Submit"> 
</form>
