[英]How to select checkbox in database mysqli table in PHP
**如何在數據庫mysqli中選擇復選框,我應該在復選框值中寫些什么,請幫助我也內爆將數組轉換為字符串的函數,但找不到要打印的復選框值的函數。 .....還要檢查圖片上的輸出... **
<?php
while($fetch=mysqli_fetch_array($select))
{
?>
<tr>
<td><?php echo $fetch["tableno"]?></td>
<td><?php echo $fetch["customerid"]?></td>
<td><?php echo $fetch["item"]?></td>
<td><?php echo $fetch["money"]?></td>
<td><a href="javascript:del_tableno(<?php echo $fetch["tableno"];?>)"><button>Delete</button></a></td>
<td><a href="update.php?tableno=<?php echo $fetch["tableno"]; ?>"/><button>Update</button></td>
<td><form method="POST">
<input type="checkbox" name="chk[]" value="???">
<input type="submit" name="sub1" value="Button for Checkbox">
</td> </form>
</tr>
<?php
}?>
</table>
<p style="font-size:30px">The Customer has TO Selected these Items from Menu List
and therefore submitted to<br> Kitchener to Make the Food and
then waiter will serve the Food to Customer.</p>
</body>
</html>
<?php
if(isset($_POST['sub1']))
{
$chk=implode(',', $_POST['chk']);
echo "<br>Customer has selected the following checkbox Item to be Prepared and Eat the Food:<br/>";
echo "<br/>".$chk."<br><br/><br/><br/><br/>";
}
?>
嘗試這個:
在您的表單中,插入多個復選框的方法
<form method="POST" action="test2.php">
<input type="checkbox" name="chk[]" value="InputText1">InputText1<br>
<input type="checkbox" name="chk[]" value="InputText2">InputText2<br>
<input type="submit" name="sub1">
</form>
if(isset($_POST['sub1'])) // check the submitted form and print the values
{
echo "You selected the following checkbox:<br/>";
foreach ($_POST['chk'] as $value) {
echo $value."<br>";
}
一種方法是將復選框的值與所有數據連接起來,並在提交后,為每個循環檢查選中的復選框,並打印所有選中的行。 像下面
<input type="checkbox" name="chk[]" value="<?php echo "<td>".$fetch["tableno"]."</td><td>".$fetch["customerid"]."</td><td>".$fetch["item"]."</td><td>".$fetch["money"]."</td>"; ?>">
在發布后使用此:
if(isset($_POST['sub1'])) // check the submitted form and print the values
{
echo "Below Customers have placed orders:<br/>";
echo "<table>";
foreach ($_POST['chk'] as $value) {
echo "<tr>".$value."</tr>";
}
echo "</table>";
}
