问题描述

我正在用php脚本编写html表单代码

这里是

  如果一个表单是 method =GET（这是默认），然后提交它将清除操作中现有的查询字符串。
 
 
 将数据存储在隐藏输入中。
 <？php 
 $ problem_code =STR; 
？> 
< form name =submit-buttonaction =/ codejudge / submit.php> 
< input type =hiddenname =idvalue =<？php echo htmlspecialchars（$ problem_code）;？>> 
< button type =submit>提交< / button> 
< / form> 
  
 
i am writing html form code with in php script 
here it is
<?php
  $problem_code="STR";
  echo '<form name="submit-button" action="/codejudge/submit.php?id='.$problem_code.'">';
  echo '<button type="submit" >Submit</button>';
  echo "</form>";
?>
But after submitting url look like this localhost/codejudge/submit.php ?but it should be like this localhost/codejudge/submit.php?id=STR 
 解决方案 
If a form is method="GET" (which is the default), as this one is, then submitting it will erase the existing query string in the action.
Store the data in a hidden input instead.
<?php
  $problem_code="STR";
?>
<form name="submit-button" action="/codejudge/submit.php">
  <input type="hidden" name="id" value="<?php echo htmlspecialchars($problem_code); ?>">
  <button type="submit">Submit</button>
</form>
