Question

   $searchquery = mysql_query("SELECT * FROM regform_admin WHERE status = 'Approved' AND month LIKE '%".$checkmonth."%' AND day LIKE '%".$checkday."%' AND year LIKE '%".$checkyear."%' OR month2 LIKE '%".$checkmonth."%' AND day2 LIKE '%".$checkday."%' AND year2 LIKE '%".$checkyear."%' OR betday LIKE '%".$checkday."%'");
            while($fetchres = mysql_fetch_array($searchquery)) { 
            $vehicles = $fetchres['vehicles']; 
            echo "<b>$vehicles</b><br>";
                    }

include "vehicledbconnect.php";
$searchquery2 = mysql_query("SELECT * FROM vehicletbl WHERE vehicle NOT LIKE '%".$vehicles."%'");

    while($fetch = mysql_fetch_array($searchquery2)) {
    $v = $fetch['vehicle']; 
    $vehed = $fetch['vehed']; $vehcap = $fetch['vehcap']; $vehyr = $fetch['vehyr']; 
    $type = $fetch['type']; 
        echo "<tr>";
        echo "<td class=light><input type = 'checkbox' name='chk[]'></td>";
        echo "<td class=light>$v</td>";
        echo "<td class=light>$type</td>";
        echo "<td class=light>$vehyr</td>";
        echo "<td class=light>$vehed</td>";
        echo "<td class=light>$vehcap</td>";
        echo "<td class=light>$vehcolor</td>";
        echo "</tr>";   
        echo "$array";
            }

是否可以在$ searchquery2内的$ searchquery中回显while语句中的所有值？

例如$ searchquery的值是：

vehicle1
vehicle2
vehicle3

现在我要在$ searchquery2内回复所有内容，是否可能？我尝试在$ searchquery2中回显$ vehicles（来自$ searchquery），但它只回显最后一个值（例如.carve3），因为我知道它不在$ searchquery的while语句中。

有可能吗？感谢。

Answer 1

在循环中构建循环。

试试这个：

mysql_query("SELECT * FROM regform_admin WHERE...")
while(...)
{
   $vehicles = $fetchres['vehicles'];
   echo "<b>$vehicles</b><br>";

   mysql_query("SELECT * FROM vehicletbl WHERE vehicle NOT LIKE '%".$vehicles."%'");
   while(...)
   {
       echo ...
   }

}

Answer 2

而不是echo在while循环中，尝试将输出缓冲到变量：

$ob = '';
while($fetchres = mysql_fetch_array($searchquery)) 
    $ob .= '<b>' . $fetchres['vehicles'] . '</b><br>';
echo($ob);

在第二次while循环期间，$ob仍处于活动状态，您可以轻松地将其回显。在这里，我将其存储为字符串，但如果您需要对元素进行更细粒度的访问，也可以将值存储为数组。

如果您想将它们存储到数组中，请尝试这种方式：

$ob = array();
while($fetchres = mysql_fetch_array($searchquery)) 
    $ob[] = $fetchres['vehicle'];  // This pushes the current vehicle onto the end of the array

在这个循环之后，你只需要数组中每个车辆的字符串，而不是格式化。您可以在输出元素时添加它。使用foreach：

对数组进行迭代

foreach($ob as $k => $v) {
    // Inside this loop, $k is the key, or index, and $v is the value.
    // You can change the names of these variables by modifying the line above, e.g. 
    // foreach($ob as $foo => $bar)  <-- $foo = key/index, $bar = value
}

在语句外调用多个值
