PHP - 雖然循環更改

Question

我有以下while while循環。

$readNews_SQLselect = "SELECT "; 
$readNews_SQLselect .= "id, content "; // rows names 
$readNews_SQLselect .= "FROM "; 
$readNews_SQLselect .= "news ";   // table name 


$readNews_SQLselect_Query = mysql_query($readNews_SQLselect); 

//$indx = 1;  
while ($row = mysql_fetch_array($readNews_SQLselect_Query, MYSQL_ASSOC)) { 
    $ID = $row['id']; 
    $CONTENT = $row['content']; 

    echo '<li>' . $ID .' ' . $CONTENT . '</li>'; 

    //$indx++; 

} 

mysql_free_result($readNews_SQLselect_Query); 

會如何看待，如果我加入'$LIVE = $row['live'];'與條件只能用「0」 live值的字符串行應顯示？直播將是0/1（VARCHART）。

任何建議非常感謝。

Answer 1

只需添加到您的查詢：

$readNews_SQLslect .= " WHERE live = '0'"; 

Answer 2

阿爾特$readNews_SQLselect

$readNews_SQLselect = "SELECT "; 
$readNews_SQLselect .= "id, content "; // rows names 
$readNews_SQLselect .= "FROM "; 
$readNews_SQLselect .= "news ";   // table name 
$readNews_SQLselect .= "WHERE live='0'"; // condition 

Answer 3

1. 改變你的SQL：

   $readNews_SQLselect = "SELECT "; 
   $readNews_SQLselect .= "id, content "; // rows names 
   $readNews_SQLselect .= "FROM "; 
   $readNews_SQLselect .= "news ";   // table name 
   $readNews_SQLselect .= "where live = '0' ";

2. 如果條件：

   if ($row['live'] == '0') { echo '<li>' . $ID .' ' . $CONTENT . '</li>'; }
