在將許多表單數據提交到php文件之后，php文件如何接收該數據輸入？

Question

我的html代碼-在表單結構中，有1個data-role =“ collapsible-set”和許多data-role =“ collapsible”。 有很多復選框，如下面的代碼。

 <form action="sx_oriented.php" method="get" id="symptom">
            <div data-role="collapsible-set">
              <div data-role="collapsible">
                <h3>Circulatory and Respiratory systems? Click me!</h3>

                   <fieldset data-role="fieldcontain">
                    <label for="symptom">Select your Symptoms</label>
        <table>                      
        <tr><th><input type="checkbox" name="r_code[]"  value="R00"></th><th> Abnormalities of heart beat</th></tr>
        <tr><th><input type="checkbox" name="r_code[]"  value="R00.0"></th><th> Tachycardia, unspecified</th></tr>
        <tr><th><input type="checkbox" name="r_code[]"  value="R00.1"></th><th> Bradycardia, unspecified</th></tr>
        <tr><th><input type="checkbox" name="r_code[]"  value="R00.2"></th><th> Palpitations</th></tr>
        <tr><th><input type="checkbox" name="r_code[]"  value="R00.8"></th><th> Other and unspecified abnormalities of heart beat</th></tr>
        <tr><th><input type="checkbox" name="r_code[]"  value="R01"></th><th> Cardiac murmurs and other cardiac sounds</th></tr>
        <tr><th><input type="checkbox" name="r_code[]"  value="R01.0"></th><th> Benign and innocent cardiac murmurs</th></tr>
        <tr><th><input type="checkbox" name="r_code[]"  value="R01.1"></th><th> Cardiac murmur, unspecified</th></tr>
       </table>
       </div> 

       <div data-role="collapsible">
              <h3>Digestive system and abdomen? Click me!</h3>

                              <fieldset data-role="fieldcontain">
                                <label for="r_code[]">Select r_code[]</label>
         <table>
             <tr><th><input type="checkbox" name="r_code[]"  value="R10"></th><th> Abdominal and pelvic pain</th></tr>
        <tr><th><input type="checkbox" name="r_code[]"  value="R10.0"></th><th> Acute abdomen</th></tr>
        <tr><th><input type="checkbox" name="r_code[]"  value="R10.1"></th><th> Pain localized to upper abdomen</th></tr>
        <tr><th><input type="checkbox" name="r_code[]"  value="R10.10"></th><th> Abdomen pain, Right upper quadrant</th></tr>
        <tr><th><input type="checkbox" name="r_code[]"  value="R10.11"></th><th> Abdomen pain, Left upper quadrant</th></tr>
        <tr><th><input type="checkbox" name="r_code[]"  value="R10.12"></th><th> Epigastric pain</th></tr>
        <tr><th><input type="checkbox" name="r_code[]"  value="R10.19"></th><th> Upper abdominal pain, unspecified</th></tr>
        <tr><th><input type="checkbox" name="r_code[]"  value="R10.2"></th><th> Pelvic and perineal pain</th></tr>
        <tr><th><input type="checkbox" name="r_code[]"  value="R10.3"></th><th> Pain localized to other parts of lower abdomen</th></tr>
        <tr><th><input type="checkbox" name="r_code[]"  value="R10.30"></th><th> Abdomen pain, Right lower quadrant</th></tr>
        <tr><th><input type="checkbox" name="r_code[]"  value="R10.31"></th><th> Abdomen pain, Left lower quadrant</th></tr>
        <tr><th><input type="checkbox" name="r_code[]"  value="R10.32"></th><th> Periumbilical pain</th></tr>
       </table>
      </div>
          ----10 more "collapsible"---
      <input type="submit" value="submit">
     </form>

然后，執行action =“ sx_directional.php”，如下所示

    <?php
    $checked = $_GET['r_code'];
    for($i=0; $i < count($checked); $i++){
   echo "Selected " . $checked[$i] . "<br/>";
   }
   ?>

但是，我沒有結果！ 為什么不？？ 請幫我！！

Answer 1

首先，我將在表單中使用POST 。 因此，將method="get"更改為method="POST" 。

然后，您可以執行此操作。

<?php

    $checked = $_POST['r_code'];

    if(isset($checked)){
      foreach($checked as $check){
      echo "Selected ".$check."<br />"; 
      }
    }

?>
