我有一些select选项，我分页显示每页显示5个选项，这样就可以了。

    <form method="post" action="sel.php">
    <?php

//Pagination script here

//Here, I retrieve some values from database 
    $sql = "SELECT * FROM games WHERE startunix > '$nowtime' ORDER BY starttime LIMIT $offset, $rowsperpage" ;
    $retval = mysql_query($sql);
    while($row = mysql_fetch_array($retval, MYSQL_ASSOC))
    {

//Here, I display the select option while the above values are retrived

 echo "<div align='center'><span class='style3'>{$row['home']} VS ".
             "{$row['away']} </span></div>".
             "<font color='#000000' size='2'>{$row['country']} | {$row['league']} | Time:{$row['starttime']} </font> <br> ".
             "<select name='gm[$row[gamecode]|$row[starttime]|$row[home]|$row[away]]' >
             <option value=''>Select option</option>
    <option value='1.80 01 Both Team to Score (YES)'>1.90 Both Team to Score (YES)</option>

$range = 3;

// if not on last page, show forward and last page links        
if ($currentpage != $totalpages) {

问题在于，如果用户在第1页上选择任意数量的选项，然后单击第2页，并在第2页上选择选项，则在第3页上不选择任何内容并继续提交表单，只选择在在表单处理页面上检索最后一个选择页面，即页面2。如何将所有页面中选择的选项值传递到表单处理页面，而不仅仅是最后一页上选择的值？

Answer 1

有几种方法可以传递所选的选项。

使用Get方法（如果在URL中传递信息没有坏处）

您可以在网址中传递所选的值，例如example.com/?option=true&option2=true 并且可以检索，即使用isset（）函数检查选项是否被选中例如。 if(isset($_GET["option"])) { //do some stuffs }或if($_GET["option"]=="true") { //do some stuffs }

使用POST方法

上述方法存在很小的差异，得到和发布一个。您需要在每种情况下将$_GET更改为$_POST

其他两种方法，你可以使用我不推荐的cookie和会话

如何在提交表单php后通过分页页面检索所有选定的选项
