Question

我正在尝试制作一个可以在我的某些帖子上添加视频的功能。

我正在使用这个功能：

function singleVideo($id = '') {
    $id = mysql_real_escape_string ($id);
    $sql = "SELECT post_excerpt,vid,file FROM wp_posts,wp_wordtube WHERE post_excerpt = vid ";
    $res = mysql_query($sql) or die (mysql_error());    

if (mysql_num_rows($res) !=0):
    $row = mysql_fetch_assoc($res);

    echo "      
<object classid='clsid:D27CDB6E-AE6D-11cf-96B8-444553540000' width='640' height='360' id='single1' name='single1'>
<param name='movie' value='videos/player.swf'>
<param name='allowfullscreen' value='false'>
<param name='allowscriptaccess' value='always'>
<param name='wmode' value='transparent'>
<param name='flashvars' value='file=".$row['file']."'>
<embed
type='application/x-shockwave-flash'
id='single2'
name='single2'
src='videos/player.swf'
width='640'
height='360'
bgcolor='undefined'
allowscriptaccess='always'
allowfullscreen='false'
wmode='transparent'
flashvars='file=".$row['file']."'
/>
</object>
    "; //echo

    else:
        echo 'This page dont exist';
    endif;
} // end

但是有一个问题，即使object t为0，每个帖子都会显示post_excerp。

所以我要问的是：

我希望功能singleVideo()仅显示在post_excerpt！= 0或null

感谢您阅读..

EDITED

我已经改变了我的功能，但它现在没有显示任何类型的视频!!

function singleVideo($id = '') {
    $id = mysql_real_escape_string ($id);
    $sql = "SELECT * FROM wp_posts,wp_wordtube WHERE ID='$id' AND post_excerpt = vid ";
    $res = mysql_query($sql) or die (mysql_error());    

    $row = mysql_fetch_assoc($res);

if($row["post_excerpt"] != 0) {
        echo "
        <object classid='clsid:D27CDB6E-AE6D-11cf-96B8-444553540000' width='640' height='360' id='single1' name='single1'>
<param name='movie' value='videos/player.swf'>
<param name='allowfullscreen' value='false'>
<param name='allowscriptaccess' value='always'>
<param name='wmode' value='transparent'>
<param name='flashvars' value='file=".$row['file']."'>
<embed
type='application/x-shockwave-flash'
id='single2'
name='single2'
src='videos/player.swf'
width='640'
height='360'
bgcolor='undefined'
allowscriptaccess='always'
allowfullscreen='false'
wmode='transparent'
flashvars='file=".$row['file']."'
/>
</object>

";

}

} // end

Answer 1

这样的东西？

$ sql =“SELECT post_excerpt，vid，file FROM wp_posts，wp_wordtube WHERE post_excerpt = vid AND post_excerpt！= 0“;

Answer 2

function singleVideo($id = '') {
        $id = mysql_real_escape_string ($id);
        $sql = "SELECT post_excerpt,vid,file FROM wp_posts,wp_wordtube WHERE post_excerpt = vid ";
        $res = mysql_query($sql) or die (mysql_error());    

        $row = mysql_fetch_assoc($res);
    if($row["post_excerpt"] != 0 && !is_null($row["post_excerpt"])){
        echo "      
    <object classid='clsid:D27CDB6E-AE6D-11cf-96B8-444553540000' width='640' height='360' id='single1' name='single1'>
    <param name='movie' value='videos/player.swf'>
    <param name='allowfullscreen' value='false'>
    <param name='allowscriptaccess' value='always'>
    <param name='wmode' value='transparent'>
    <param name='flashvars' value='file=".$row['file']."'>
    <embed
    type='application/x-shockwave-flash'
    id='single2'
    name='single2'
    src='videos/player.swf'
    width='640'
    height='360'
    bgcolor='undefined'
    allowscriptaccess='always'
    allowfullscreen='false'
    wmode='transparent'
    flashvars='file=".$row['file']."'
    />
    </object>
        ";
    } else{
            echo 'This page dont exist';
    }
    }

显示功能只有一些帖子？
