PHP表单不发送GET [重复]

Question

This question already has an answer here:

• “Notice: Undefined variable”, “Notice: Undefined index”, and “Notice: Undefined offset” using PHP 28 answers

So I'm working on a searchfunction for my webwshop and I've gotten pretty far. I've set the GET function up with the SELECT code on the search.php file. So I "pretty confidently" thought lets just quickly do the form and I'm done....

Well not so easy as it turns out. I've got this code now and I can't seem to send the data with the get. When you search something now all you get is http://buitenlandseproducten.nl/search.php?id= but nothing stored in the id.

  <div class="form-group">
    <span class="col-md-1 col-md-offset-1 text-center"><i class="fa fa-envelope-o bigicon"></i></span>
    <div class="col-md-8">
      <input id="form" name="form" type="text" placeholder="Search" class="form-control" >
    </div>
    <div class="col-md-12 text-center">
      <?php
        echo '<p>'. '<a href="search.php?id='.$_POST['form'].'">' . '<button type="submit" class="btn btn-secondary">' . 'Search' . '</button>' . '</a>' . '<br />';
      ?>
    </div>
  </div>

If someone could help me out here you'll be my hero forever! Help would be greatly appreciated!!

<form method="GET" action="search.php">
<input id="form" name="id" type="text" placeholder="Search" class="form-control" />
<input type='Submit' Value="Search!"/>
</form>

This should give you what i want.

<div class="form-group">
    <span class="col-md-1 col-md-offset-1 text-center"><i class="fa fa-envelope-o bigicon"></i></span>
    <div class="col-md-8">
         <form method="GET" action="search.php">
<input id="form" name="id" type="text" placeholder="Search" class="form-control" />
<input type='Submit' Value="Search!"/>
</form>
    </div>
    <div class="col-md-12 text-center">
      <?php
       // I don't know why you have this echo below here, its not necessary for what you're trying 
// echo '<p>'. '<a href="search.php?id='.$_POST['form'].'">' . '<button type="submit" class="btn btn-secondary">' . 'Search' . '</button>' . '</a>' . '<br />';
      ?>
    </div>
  </div>

The href element to link to the search.php and create a get field and assign a value to it from A POST field is kind of stretching it, and not a real smart way to go about doing it. Good luck to you, you'll need it :)
