合并来自单个表的查询

Question

我有 2 个查询。 第一个查询获取产品标题，第二个查询获取产品图片并创建网格布局。 两个查询都在 1 个表上进行查找。

$sql = "SELECT post_title FROM `wordpress`.`wp_posts` ".
          "WHERE post_type ='wpsc-product' ".
          "AND post_status = 'publish' ORDER BY `wp_posts`.`ID`"; 
$result = mysql_query($sql) or die(mysql_error()); 
while($row = mysql_fetch_array($result)){

    $title = $row['post_title']; 
}

$sql2 = "SELECT guid FROM `wordpress`.`wp_posts` ".
        "WHERE post_mime_type ='image/png' ORDER BY `wp_posts`.`ID`"; 
echo "<table border=\"10\" style=\"margin-top:10px;\">"; 
echo "<tr>"; 
$i=1; 
$result2 = mysql_query($sql2) or die(mysql_error()); 


while($row2 = mysql_fetch_array($result2) ){ 

    $image = $row2['guid']; 
    echo "<td><a href=".$image.">".
         "<IMG style=\"width:100px;height:100px;".
                      "vertical-align:top; padding-right: 10px; " . 
                       ( ($i %2 == "0") ? "padding-left: 30px;" : "") . 
        "  \" SRC=\"$image\" ALT=\"align box\" ALIGN=LEFT></a>"; 

    echo "<a style=\"text-decoration:underline;\" ".
             "onmouseover=\"this.style.textDecoration = 'none'\" ".
             "onmouseout=\"this.style.textDecoration = 'underline'\"".
             "href=".$lol.">$title</a><br>"; 
    echo "<p style=\"color:#990000; padding-top:5px; font-weight:bold;\">".
           " $19.90</p> <a style=\"font-weight:lighter;\" href=".$lol.">".
           "More info<img style=\"padding-left:3px;\" ".
            "src=\"http://localhost/famfamfam.png\"></a></td>"; 
    if ($i++ % 2 == 0) { 
       echo "</tr><tr><td style=\"padding-right:20px;\" colspan=\"1\">".
            "<hr style=\"width:250px;\" /></td> ".
            "<td style=\"padding-right: 20px; padding-left: 30px;\" ".
            "colspan=\"1\"><hr style=\"width:250px;\" /></td></tr>"; 
    } 
} 
echo "</tr></table>"; 

我想使用第一个查询（$title）的结果并在第二个while循环查询（$title）中使用它。

我怎么做。 提前致谢。

更新

@Muhammad Yasir 和@cwallenpoole 你们俩的回答都不起作用，但我更喜欢@cwallenpoole 的想法，因为您使用单个查询。 这是你们两个人回答的图像 output。 一样： http://i.imgur.com/pf01M.png

我实际上设法用 php 过滤结果，但我希望我可以用 sql 来优化查询结果。

 $sql2 = "SELECT * FROM `wordpress`.`wp_posts`";  
echo "<table border=\"10\" style=\"margin-top:10px;\">";  
echo "<tr>";  
$i=1;  
$result2 = mysql_query($sql2) or die(mysql_error());  


while($row2 = mysql_fetch_array($result2) ){  

if ($row2['post_status'] == 'publish' && $row2['post_type'] == 'wpsc-product'){ 
       $title = $row2['post_title']; 
} 

//echo  $row2['guid']; 

if ($row2['post_mime_type'] == 'image/png' ) 
{ 
$image = $row2['guid']; 



            echo "<td><a href=".$image."><IMG style=\"width:100px;height:100px;vertical-align:top; padding-right: 10px; " . ( ($i %2 == "0") ? "padding-left: 30px;" : "") . "  \" SRC=\"$image  \" ALT=\"align box\" ALIGN=LEFT></a>";  

    echo "<a style=\"text-decoration:underline;\" onmouseover=\"this.style.textDecoration = 'none'\" onmouseout=\"this.style.textDecoration = 'underline'\" href=".$lol."> $title  </a><br>";  
    echo "<p style=\"color:#990000; padding-top:5px; font-weight:bold;\"> $19.90</p> <a style=\"font-weight:lighter;\" href=".$lol.">More info<img style=\"padding-left:3px;\" src=\"http://localhost/famfamfam.png\"></a>  
</td>";  
    if ($i++ % 2 == 0) {  
       echo "</tr><tr><td style=\"padding-right:20px;\" colspan=\"1\"><hr style=\"width:250px;\" /></td> <td style=\"padding-right: 20px; padding-left: 30px;\" colspan=\"1\"><hr style=\"width:250px;\" /></td></tr>";  
    }  
} 




}  
echo "</tr></table>"; 

和我想要的 output： http://i.imgur.com/Vjq2Q.png

这是 sql 文件。 我希望有人可以帮助我优化我的代码。

Answer 1

使用像$j这样的计数器变量：

$j = 0;    
while($row2 = mysql_fetch_array($result2) ){ 
    $t = $title[$j]; // this will be your title
    $image = $row2['guid']; 
    echo "<td><a href=".$image."><IMG style=\"width:100px;height:100px;vertical-align:top; padding-right: 10px; " . ( ($i %2 == "0") ? "padding-left: 30px;" : "") . "  \" SRC=\"$image\" ALT=\"align box\" ALIGN=LEFT></a>"; 

    echo "<a style=\"text-decoration:underline;\" onmouseover=\"this.style.textDecoration = 'none'\" onmouseout=\"this.style.textDecoration = 'underline'\" href=".$lol.">$title</a><br>"; 
    echo "<p style=\"color:#990000; padding-top:5px; font-weight:bold;\"> $19.90</p> <a style=\"font-weight:lighter;\" href=".$lol.">More info<img style=\"padding-left:3px;\" src=\"http://localhost/famfamfam.png\"></a> 
</td>"; 
    if ($i++ % 2 == 0) { 
       echo "</tr><tr><td style=\"padding-right:20px;\" colspan=\"1\"><hr style=\"width:250px;\" /></td> <td style=\"padding-right: 20px; padding-left: 30px;\" colspan=\"1\"><hr style=\"width:250px;\" /></td></tr>"; 
    }
    $j++;
}

Answer 2

我认为您不需要第一个查询。 我认为你可以逃脱：

// use instead of your second query... notice the addition of post_title.
$sql2 = "SELECT guid, post_title FROM `wordpress`.`wp_posts` ".
    "WHERE post_mime_type ='image/png' ORDER BY `wp_posts`.`ID`"; 

// later! (you've done stuff in the meanwhile!)
// note: assoc is used because it is technically more appropriate
while($row2 = mysql_fetch_assoc($result2) ){ 

    $image = $row2['guid']; 
    // this will always be the title which goes with the guid!
    $title = $row2['post_title'];
