PHP+HTML-如果存在，则隐藏按钮 - PHP+HTML - If Else, Hide Button

PHP+HTML - If Else, Hide Button

这是我的php代码：

if ($value = $rec['ip'] <= $cphigh_ip && $cplow_ip <= $value = $rec['ip'])
{
    $cpyes="on ";
    $realString = $value = $rec['ip'];
    $whmLink=$realString[strlen($realString)-1];
}
else
{
    $cpno="not on cPanel";
}

我的HTML表非常简单：

<tr>
    <td>Domain IP:</td>
    <td><?=$ipyes.$ipno.$cpyes.$cpno;?><input type="submit" name="cPanelButton" onClick="window.location.href='https://cp<?=$whmLink; ?>.skycomp.ca:2087'" value="cPanel"></td>
</tr>

有没有办法把按钮隐藏在else子句中？或者甚至在if语句中创建特定的按钮？

几种不同的方法之一是设置标志：

$show_button = TRUE;
if ($value = $rec['ip'] <= $cphigh_ip && $cplow_ip <= $value = $rec['ip'])
{
    $cpyes="on ";
    $realString = $value = $rec['ip'];
    $whmLink=$realString[strlen($realString)-1];
} else {
    $show_button = FALSE;
    $cpno="not on cPanel";
}

然后，在HTML中，将其包装在if条件中：

<?php if ($show_button) { ?>
    <tr>
        <td>Domain IP:</td>
        <td><?=$ipyes.$ipno.$cpyes.$cpno;?><input type="submit" name="cPanelButton" onClick="window.location.href='https://cp<?=$whmLink; ?>.skycomp.ca:2087'" value="cPanel"></td>
    </tr>
<?php } ?>

这将隐藏整个ROW。如果你只想隐藏按钮，那么：

<tr>
    <td>Domain IP:</td>
    <td><?php if ($show_button) { ?><?=$ipyes.$ipno.$cpyes.$cpno;?><input type="submit" name="cPanelButton" onClick="window.location.href='https://cp<?=$whmLink; ?>.skycomp.ca:2087'" value="cPanel"><?php } ?></td>
</tr>

您可以将按钮放入php代码

if ($value = $rec['ip'] <= $cphigh_ip && $cplow_ip <= $value = $rec['ip'])
    {
        $cpyes="on ";
        $realString = $value = $rec['ip'];
        $whmLink=$realString[strlen($realString)-1];
        $ifwhmlink = '<input type="submit" name="cPanelButton"   onClick="window.location.href=''https://cp'.$whmLink.'.skycomp.ca:2087''" value="cPanel">';
    }
    else
    {
        $cpno="not on cPanel";
        $ifwhmlink = "";
    }

<tr>
    <td>Domain IP:</td>
    <td><?=$ipyes.$ipno.$cpyes.$cpno.$ifwhmlink;?></td>
</tr>
