Question

分页用POST应该怎么处理

Answer 1

解决方案：
使用$_REQUEST代替$_POST，$_REQUEST既可用于POST方法传递来的参数
也可用于GET方法传递的参数
step2 对form的post参数在换页时要重新传递
例子：
form:
<form method="post" action="searchresult.php">
<table class="core" style="text-indent: 2em;">
<tbody>
<tr>
<td>
<p><input type="radio" name="extent" value="category">By category.

tegory">
