的foreach循环，并声明如果

Question

我有一个通过阵列应该循环，但不输出这个foreach语句：

[复选框]东西在这里

这反而输出这样的：

[复选框] [复选框]这里的东西

基本上，if语句不会被跳过，但foreach循环正在查看我的数组中的值（在这种情况下，我只有2用于测试目的）和处理他们在同一时间代替分开。我做了一些回声测试，这就是发生了什么，但为什么？

$ blogID将拥有数组值56,57，因为循环同时处理两个值，所以if语句中的两个选项都变为true，因为56等于56，但56不等于57第二遍，所以它会将if语句的后半部分处理为真。这很奇怪，我以前从未有过这种情况。

下面是代码：

$getblog = mysql_query("SELECT * FROM content WHERE blogID = '{$_REQUEST['id']}' AND type = '5' ORDER BY `order` ASC"); 
while ($row = mysql_fetch_assoc($getblog)){ 
$blogID = $row['id'];  
$tempData[$blogID][] = $row; 

$data = $_REQUEST['blogIDS']; 
$ids = explode(",", $data); 

foreach($ids as $blogIDS) { 
    $getblogids = mysql_query("SELECT * FROM content WHERE id = '$blogIDS' AND type = '5' ORDER BY `order` ASC"); 
    while ($row2 = mysql_fetch_assoc($getblogids)){ 
     $blogIDS = $row2['id'];  
     $tempData2[$blogIDS][] = $row2; 
    } 
} 
    if ($row['id'] == $blogIDS) { 
      echo "<input type='checkbox' name='ids[]' value='{$row['id']}' checked='yes'/>\n"; 
    } else { 
      echo "<input type='checkbox' name='ids[]' value='{$row['id']}'/>\n"; 
    } 

    echo "<a class='heriyah_text1' href='manage_blogposts_add.php?resize=1&edit=1&id={$row['id']}&blogID={$_REQUEST['id']}&pageID={$_REQUEST['pageID']}&div={$_REQUEST['div']}'>{$row['title']}</a><p></p>\n"; 
} 

Answer 1

编辑。试试这个，让我知道：

$getblog = mysql_query("SELECT * FROM content WHERE blogID = '{$_REQUEST['id']}' AND 
         type = '5' ORDER BY `order` ASC"); 
while ($row = mysql_fetch_assoc($getblog)){ 
    $blogID = $row['blogID'];  
    $tempData[$blogID][] = $row; 
} 

$data = $_REQUEST['blogIDS']; 
$ids = explode(",", $data); 

foreach($ids as $blogID) { 
    if (array_key_exists($blogID, $tempData)) { 
     foreach($tempData[$blogID] as $key => $value) { 
      if ($value['blogID'] == $blogID) { 
       echo "<input type='checkbox' name='ids[]' value='{$value['id']}' checked='yes'/>\n"; 
      } else { 
       echo "<input type='checkbox' name='ids[]' value='{$value['id']}'/>\n"; 
      } 

      echo "<a class='heriyah_text1' href='manage_blogposts_add.php?resize=1&edit=1&id={$value['id']}&blogID={$_REQUEST['id']}&pageID={$_REQUEST['pageID']}&div={$_REQUEST['div']}'>{$value['title']}</a><p></p>\n"; 
     } 
    } 
} 

Answer 2

你可以这样做一个相反：

$getblog = mysql_query("SELECT * FROM content WHERE blogID = '{$_REQUEST['id']}' AND 
        type = '5' ORDER BY `order` ASC"); 
while ($row = mysql_fetch_assoc($getblog)){ 
    $tempData[] = $row; 
} 

$data = $_REQUEST['blogIDS']; 
$ids = explode(",", $data); 

foreach($ids as $blogID) { 
    foreach($tempData as $key => $value){ 
     if($value['id'] == $blogID){ 
     echo "<input type='checkbox' name='ids[]' value='{$value['id']}' checked='yes'/>\n"; 
     }else{ 
     echo "<input type='checkbox' name='ids[]' value='{$value['id']}'/>\n"; 
     } 

     echo "<a class='heriyah_text1' href='manage_blogposts_add.php?resize=1&edit=1&id={$value['id']}&blogID={$_REQUEST['id']}&pageID={$_REQUEST['pageID']}&div={$_REQUEST['div']}'>{$value['title']}</a><p></p>\n"; 
    } 
}
