我有一个名为Quizes.php的主页,其中包含一个显示页面列表的分页脚本,即[1] [2] [3] .....我的代码与<a href ....>
正常工作包含指向&#34;下一步&#34;,&#34;上一页&#34;的链接&#34;最后&#34;和&#34;第一&#34;但在'<form method="get" action="?page=".$next."" >';
提交按钮不起作用。看起来action="?page=".$next.""
是错误的。那么最好的方法是什么?
我也会遇到这些链接PHP: Pagination with submit button,Submit form in a displaytag pagination以及其他但没有帮助。
<?php
$page = $_GET['page'];
if($page == ""){
$page = "1";
}else{
// If page is set, let's get it
$page = $_GET['page'];
}
// Now lets get all messages from your database
$sql = "SELECT * FROM quizes";
$query = mysql_query($sql);
// Lets count all messages
$num = mysql_num_rows($query);
// Lets set how many messages we want to display
$per_page = "2";
// Now we must calculate the last page
$last_page = ceil($num/$per_page);
echo 's', $num;
// And set the first page
$first_page = "1";
// Here we are making the "First page" link
echo "<a href='?page=".$first_page."'>First page</a> ";
// If page is 1 then remove link from "Previous" word
if($page == $first_page){
echo "Previous ";
}else{
if(!isset($page)){
echo "Previous ";
}else{
// But if page is set and it's not 1.. Lets add link to previous word to take us back by one page
$previous = $page-1;
echo "<a href='?page=".$previous."'>Previous</a> ";
}
}
// If the page is last page.. lets remove "Next" link
if($page == $last_page){
echo "Next ";
}else{
// If page is not set or it is set and it's not the last page.. lets add link to this word so we can go to the next page
if(!isset($page)){
$next = $first_page+1;
echo "<a href='?page=".$next."'>Next</a> ";
}else{
$next = $page+1;
echo "<a href='?page=".$next."'>Next</a> ";
}
}
// And now lets add the "Last page" link
echo "<a href='?page=".$last_page."'>Last page</a>";
// Math.. It gets us the start number of message that will be displayed
$start = ($page-1)*$per_page;
// Now lets set the limit for our query
$limit = "LIMIT $start, $per_page";
// It's time for getting our messages
$sql = "SELECT * FROM quizes $limit";
$query = mysql_query($sql);
echo "<br /><br />";
// And lets display our messages
$i=0;
while($row = mysql_fetch_array($query) or die(mysql_error())){
$a= $row['A'];
echo '<form method="get" action="?page=".$next."" >'; // is that correct way?????
while ($row=mysql_fetch_array($query))
{

echo "\t".'<tr><th>'.

Get方法在您想要的网址中发送数据。您不需要在操作中发送数据,否则将输入字段命名为page并将其值设置为页码。这样,当您提交时,数据将以您希望的方式提交 用这个替换你的while循环
while($row = mysql_fetch_array($query) or die(mysql_error())){
$a= $row['A'];
echo '<form method="get">';
while ($row=mysql_fetch_array($query))
{
echo '<div class="boxed" >';
echo "\t".'<tr><th>'.
$row['question']."<br>".
'</th><th>'."<input type='radio' name= '.$i' value='{$row['A']}'>".$row['A']."<br>".
'</th><th>'."<input type='radio' name='.$i' value='{$row['B']}'>".$row['B']."<br>".
'</th><th>'."<input type='radio' name='.$i' value='{$row['C']}'>".$row['C']."<br>".
'</th><th>'."<input type='radio' name='.$i' value='{$row['D']}'>".$row['D'].'</th>
</tr>';
echo '<input type="hidden" name="page" value="'.$next.'">';
echo '<input type="submit" name="submit"/>';
$i++;
echo '</div>';
echo '</div>';
}
echo '</form>';
}

看起来像语法错误。
尝试:
echo '<form method="get" action="?page='.$next.'">';
在.$next.
附近使用单引号,因为您使用了echo
的单引号。如果您使用双引号,它会关闭action
属性(解释为javascript,而不是PHP)。
此外,您可以查看PHP错误日志。

<?php
//before you begin - try to know how get works
//clean your code a bit, by mentioning form outside of while loop
//you almost get everything in print_r($_GET); after submit
//i think its better to attach data you get(value from radios,textfields) with that of the current page value(page=1)
//page - a tag - page = 1
//$string = "option1=a";
//$page = 1;
//finalstring = $string.'&'.page=$page;
//url - To next a tags http://example.com/$finalstring
?>
<form action='Quizes.php' method='GET'>
<?php
$i = 0;
//test case
while($i <= 5){
echo '<div class="boxed">';
echo "<input type='radio' name= 'ans[]' value='$i' $checked > $i";
echo '</div>';
$i++;
}
?>
<input type='submit' name='submit' value='submit'/>
</form>
