Question

好吧，我正在尝试创建支持票证系统，这应该从数据库检查Status是0还是0以上，如果它为零则应该说是Close Ticket，如果不是它应该说重新打开票证，但问题是它显示了两个按钮及其均匀的打印代码，我的意思是：

代码：

if($row > 0)
{

    $other = "SELECT * FROM `Dashboard` WHERE `ID` = '$id'";
    $result = mysqli_query($con, $other);
    $output = mysqli_fetch_array($result);
    $stanje = $row["Status"];

    echo '

    <br><div class="ticket_info">



    if($stanje == 0 ) {   <button class="lockticket" value="lockticketbutton">Close Ticket</button></a> }
    else if($stanje != 0 ) {  <button class="lockticket" value="lockticketbutton">Reopen Ticket</button></a> }

    Postavio: '.$output['Postavio'].' --- ['.$output['Naslov'].']

    </div>

    </br><div class="ticket_info2">

    '.$output['Text'].'

    </div>

    ';

    $odg = "SELECT * FROM `ticketcomments` WHERE `TicketID` = '$id'";
    $result = mysqli_query($con,$odg);
    while( $odgovor = mysqli_fetch_array($result,MYSQLI_ASSOC) )
    {

        echo '

        <br><div class="ticket_odgovor">

        Postavio: '.$odgovor['Poslao'].' --- [Odgovor na TiketID#'.$odgovor['TicketID'].']

        </div>

        </br><div class="ticket_odgovor2">

        '.$odgovor['Odgovor'].'

        </div>


        ';      
    }

Answer 1

问题是您对字符串中的按钮进行条件检查，并将其传递给echo语句。这不会被PHP视为条件，只是一个字符串。

您可以拥有多个echo语句而不会出现任何问题。尝试这样的事情：

echo '<br><div class="ticket_info">';
if($stanje == 0 ) {  
   echo ' <button class="lockticket" value="lockticketbutton">Close Ticket</button></a> ';
} else { 
   echo ' <button class="lockticket" value="lockticketbutton">Reopen Ticket</button></a>';   
}

 echo ...

老兄，你有引号问题，试试这段代码：

if($row > 0){

$other = "SELECT * FROM `Dashboard` WHERE `ID` = '$id'";
$result = mysqli_query($con, $other);
$output = mysqli_fetch_array($result);
$stanje = $row["Status"];

echo '<br><div class="ticket_info">';



if($stanje == 0 ) {   
echo '<button class="lockticket" value="lockticketbutton">Close Ticket</button></a>'; }
else if($stanje != 0 ) {  
echo '<button class="lockticket" value="lockticketbutton">Reopen Ticket</button></a>'; }

echo 'Postavio: '.$output['Postavio'].' --- ['.$output['Naslov'].']</div></br><div class="ticket_info2">'.$output['Text'].'</div>';

$odg = "SELECT * FROM `ticketcomments` WHERE `TicketID` = '$id'";
$result = mysqli_query($con,$odg);
while( $odgovor = mysqli_fetch_array($result,MYSQLI_ASSOC) )
{

    echo '

    <br><div class="ticket_odgovor">

    Postavio: '.$odgovor['Poslao'].' --- [Odgovor na TiketID#'.$odgovor['TicketID'].']

    </div>

    </br><div class="ticket_odgovor2">

    '.$odgovor['Odgovor'].'

    </div>


    ';      
}

试图从db获取状态并在div中使用它
