在PHP中的表單生成器

Question

嗨，我是一個初學者PHP deveoloper，我正嘗試創建一個表單生成器。我生成的表單有一些問題。當我點擊例如「段落」按鈕時，會生成一個表單，其中包含一個文本字段和另一個按鈕。

我想當我在生成的代碼中輸入一些文本，然後按下按鈕執行一些功能在我的情況下只是打印文本。

這是我的代碼：

<form action="" method="post"> 
    <button type="submit" name ="Paragraph">Paragraph Text</button> 
    <button type="submit" name ="MultipleChoice">Multiple Choice</button> 
    <button type="submit" name ="Name">Name</button> 
    <button type="submit" name ="Adress">Address</button> 
    <button type="submit" name ="Number">Number</button> 
    <button type="submit" name ="CheckBoxes">Checkboxes</button> 
    <button type="submit" name ="DropDown">Drop Down</button> 
    <button type="submit" name ="Phone">Phone</button> 
    <button type="submit" name ="Email">Email</button> 
</form> 

<?php 
    require_once 'addform.php'; 
    $buttons = array('Paragraph', 'MultipleChoice', 'Name', 
       'Adress', 'Number', 'CheckBoxes', 'DropDown', 'Phone', 'Email'); 
    foreach ($buttons as $button){ 
    if(isset($_POST[$button])){ 
     $title; 
     $input; 
     if($button == 'Paragraph'){ 
      ?> 
      <form action="" methods="post"> 
      Paragraph title: <input type="text" name="title"/> 
      <input type="submit" value="Create" name="create"/> 
      </form> 
      <?php 
      if(isset($_POST['title'])){ 
      $title = $_POST['title']; 
      echo $title; 
      } 
     } 
    } 
    break; 
} 
?> 

什麼我錯在這裏做什麼？

Answer 1

試試這個，它的工作原理，你已經在你的段落FO使用methods代替method rm ... 並且您還使用了錯誤的變量名submit在$_POST['']它應該是isset($_POST['create'])。

<form action="" method="post"> 
    <button type="submit" name ="Paragraph">Paragraph Text</button> 
    <button type="submit" name ="MultipleChoice">Multiple Choice</button> 
    <button type="submit" name ="Name">Name</button> 
    <button type="submit" name ="Adress">Address</button> 
    <button type="submit" name ="Number">Number</button> 
    <button type="submit" name ="CheckBoxes">Checkboxes</button> 
    <button type="submit" name ="DropDown">Drop Down</button> 
    <button type="submit" name ="Phone">Phone</button> 
    <button type="submit" name ="Email">Email</button> 
</form> 

<?php 

    $buttons = array('Paragraph', 'MultipleChoice', 'Name', 
       'Adress', 'Number', 'CheckBoxes', 'DropDown', 'Phone', 'Email'); 
    foreach ($buttons as $button){ 
    if(isset($_POST[$button])){ 
     $title; 
     $input; 
     if($button == 'Paragraph'){ 
      ?> 
      <form action="" method="post"> 
      Paragraph title: <input type="text" name="title"/> 
      <input type="submit" value="Create" name="create"/> 
      </form> 
      <?php 

     } 
    } 
    break; 
} 
    if(isset($_POST['create'])){ 

      $title = $_POST['title']; 
      echo $title; 
      } 

?>

我在這裏添加了一個隱藏輸入，這樣你可以輸入段落條件來執行代碼。

而且，你在這裏還有另外一個錯字：方法= 「郵報」但方法= 「郵報」。 它現在有效！

<form action="" method="post"> 
    <button type="submit" name ="Paragraph">Paragraph Text</button> 
    <button type="submit" name ="MultipleChoice">Multiple Choice</button> 
    <button type="submit" name ="Name">Name</button> 
    <button type="submit" name ="Adress">Address</button> 
    <button type="submit" name ="Number">Number</button> 
    <button type="submit" name ="CheckBoxes">Checkboxes</button> 
    <button type="submit" name ="DropDown">Drop Down</button> 
    <button type="submit" name ="Phone">Phone</button> 
    <button type="submit" name ="Email">Email</button> 
</form> 

<?php 
    require_once 'addform.php'; 
    $buttons = array('Paragraph', 'MultipleChoice', 'Name', 
      'Adress', 'Number', 'CheckBoxes', 'DropDown', 'Phone', 'Email'); 
foreach ($buttons as $button){ 
if(isset($_POST[$button])){ 
    $title; 
    $input; 
    if($button == 'Paragraph'){ 
     ?> 
     <form action="" methods="post"> 
     Paragraph title: <input type="text" name="title"/> 
     <input type="hidden" value="set" name="Paragraph"/> 
     <input type="submit" value="Create" name="create"/> 
     </form> 
     <?php 
     if(isset($_POST['title'])){ 
     $title = $_POST['title']; 
     echo $title; 
     } 
    } 
} 
break; 
}

如果你想要的標題來呼應你有被點擊創建按鈕時拍攝..

你創建按鈕被命名爲「創造」所以這增加了$按鈕數組，然後寫一個處理程序 '創建' 如：

$buttons = array('create', 'Paragraph', 'MultipleChoice', 'Name', 
      'Adress', 'Number', 'CheckBoxes', 'DropDown', 'Phone', 'Email'); 
foreach ($buttons as $button){ 
if(isset($_POST[$button])){ 
    $title; 
    $input; 
    if($button == 'Paragraph'){ 
     ?> 
     <form action="" methods="post"> 
     Paragraph title: <input type="text" name="title"/> 
     <input type="submit" value="Create" name="create"/> 
     </form> 
     <?php 
    }elseif($button=='create' && isset($_POST['title'])){ 
     $title = $_POST['title']; 
     echo $title; 
    } 
} 
break; 

}
