<html>
<body>
<?php
include('conn.php');
$per_page = 3;
if($_GET)
{
$page=$_GET['page'];
}
$start = ($page-1)*$per_page;
$select_table = "select * from clientreg order by id limit $start,$per_page";
$variable = mysql_query($select_table);
?>
<form name="frmUser" method="post" action="">
<div style="width:100%;">
<table border="0" cellpadding="10" cellspacing="1" width="100%" class="tblListForm">

<?php
$i=1;

我在此代碼中哪里寫錯了?
請解決我的問題
我的問題在這里
if(isset($_POST["submit"]) && $_POST["submit"]!="") {
$rowCount = count($_POST["users"]);
任何幫助將不勝感激
我已經更新了代碼並添加了提交按鈕。
您有兩種形式。 只有第二個表單具有提交。
表格1:
<form name="frmUser" method="post" action="">
<input type="checkbox" name="users[]" value="<?php echo $row["id"]; ?> ">
</form>
表格2:
<form class="form" method ="Post"action="" id="contact">
<input type="submit" name="submit" value="Submit">
</form>
if構造不接收$ _POST [“ users”],因為它僅接收第二個提交表單的POST。
$rowCount = count($_POST["users"]);
$ rowCount將始終為0。
表格2:
...
<?php
$rowCount = 0;
if ($_POST["users"] != "") {
$rowCount = count($_POST["users"]);
} else if ($_POST["rowcount"] != "") {
$rowCount = $_POST["rowcount"];
}
?>
...
<form class="form" method ="Post"action="" id="contact">
...
<input type="submit" name="submit" value="Submit">
<input type="hidden" name="rowcount" value="<?php echo $rowCount; ?>">
</form>
然后,變量$ rowCount將包含提交兩種形式中的任何一種之后的行數。
