Answer 1

while ($row = $result1->fetch_assoc()) {
    if ($row['app_cn'] != '') {
        echo '<tr>
        <td>' . $i++ . '</td>
        <td>' . $row['item_name'] . '</td>
        <td>' . $row['pr'] . '</td>

        <td align="center">';
if (!empty($row['pr'])){
    echo '<a class="fancybox" href="addpr.php?counts=' . $row["id"] . '"></a>';
}
echo'</td></tr>';
}

Answer 2

将href属性设置为"javascript:;"

Answer 3

You can use the following:

...
echo '<td align="center"><a class="fancybox" href="'.(($row['pr']!="")?'addpr.php?counts='.$row["id"]:'#'). '"></a></td>';

Answer 4

if you are trying to remove the modal (fancybox) functionality then you can do so by removing the class of the link with jquery or javascript..

example

$('a[href="PR100"]').removeClass('fancybox');

this checks each link on the page. if the link has an href attribute that is equal to PR100, we remove the fancybox class which would prevent the popup.

your question is pretty cryptic though. I'm guessing this is what youre asking..

 <?php
    echo '<table>
        <thead>
        <tr>
        <th></th>
        <th>Item Name</th>
        <th>PR</th>
        <th><Add></th>
        </tr>
        </thead>';
    echo '<tbody>';
    $i = 1;
    while ($row = $result1->fetch_assoc()) {
        if ($row['app_cn'] != '') {
            $url = $row['pr'] ? 'addpr.php?counts=' . $row['pr'] : '#';
            echo '<tr>
            <td>' . $i++ . '</td>
            <td>' . $row['item_name'] . '</td>
            <td>' . $row['pr'] . '</td>
            <td align="center"><a class="fancybox" href="{$url}"></a></td>
       </tr>';
        }
