对于k = 1，无法提交弹出表单

Question

如果我点击此按钮，

<input href="#medicine-patient1<?php echo $k; ?>" type='submit' name='form_edit<?php echo $k; ?>' class='medicine medicine-btn someClass'  value='' title="Medicine"  />

显示一个弹出窗体，`

 <div style="display:none;">
      <div id="medicine-patient1<?php echo $k; ?>" class="medicine-patient-pop">
      <form name="medicine1<?php echo $k; ?>" id="medicine1<?php echo $k; ?>" method="post" action="edit_medicine_dosage.php">
        <div class="patient-form">
          <h1>Change medicine dosage</h1>
          <?php
 $group1 = getgroupdataId($db);
$group_id = getgroupId($db,$group);
$patgrp_id = $group_id['groupid'];
//echo $group;
//echo $k;
 ?>

请不要对查询和所有问题感到恼火。问题是，如果k = 1的值，我无法提交表格。除了k = 1之外，其他任何工作都是正常的。查询工作正常。请使用不要被php代码搞糊涂。
