刷新在另一个页面中成功插入查询后的一个页面的mysql查询

标签： php jquery mysql

我正在使用以下脚本来构建图片库

1）scriptphoto.js

2）acceptcomment.php

3）edit_album.php

Edit_album.php包含一个mysql查询，该查询在图像获取单击时运行（如果共享图像则打印注释）

HTML：

<div id="photo_preview" style="display:none">
    <div class="photo_wrp">
        <img class="close" src="uploads/close.gif" />
        <div style="clear:both"></div>
        <div class="pleft">test1</div>

        <div class="pright">test2</div>
        <div style="clear:both"></div>
    </div>
</div>

和scriptphoto.js上的Javascript 

function getPhotoPreviewAjx(id,name) {
       $.post('edit_album.php',{action:'get_info',Id:id},

            function(data){
            if (name == 'YES'){
            $('#photo_preview .pleft').html(data.data1);
            $('#photo_preview .pright').html(data.data2);
            $('#photo_preview').show();

        }
            else{
            $('#photo_preview .pleft').html(data.data1);
            $('#photo_preview .pright').html(data.data3);
            $('#photo_preview').show();
            }

        }, "json"
    );
};

php_album.php上的php代码是

if ($_POST['action'] == 'get_info' && (int)$_POST['Id'] > 0) {

$iPid = (int)$_POST['Id'];

$shared = $_POST['shared'];   


       $sComments = '';

     $sq= "SELECT * FROM comment_table WHERE ImageSN = '".$iPid."' ORDER BY C_when ASC LIMIT 10";
     $sql = mysql_query($sq);
      while($query = mysql_fetch_array($sql))   
            {
                $sWhen = date('F j,Y' , $query['C_when']);
                $sComments .= "<div class=\"comment\" id='".$query['C_id']."'>
                <p>Comment from '".$query['c_name']."' <span>(".$sWhen.")</span>:</p>
                <p>".$query['c_text']."</p>
                </div>" ;

                }

        $sharewarning .="<div id='sharewarning'>Share Images To Enable Comments</div>";




       $sCommentsBlock .="<div class=\"comments\" id=\"comments\">
    <h2>Comments</h2>
    <div id=\"comments_warning1\" style=\"display:none\">Don`t forget to fill both fields (Name and Comment)</div>
    <div id=\"comment_warning2\" >You can't post more than one comment per 10 minutes (spam protection)</div>
    <form onsubmit=\"return false;\">
        <table>
            <tr><td class=\"label\"><label>Your name: </label></td><td class=\"field\"><input type=\"text\" value=\"\" title=\"Please enter your name\" id=\"name\" /></td></tr>
            <tr><td class=\"label\"><label>Comment: <input type=\"hidden\" name=\"action\" value=\"accept_comment\"></label></td><td class=\"field\"><textarea name=\"text\" id=\"text\"></textarea></td></tr>
            <tr><td class=\"label\">&nbsp;</td><td class=\"field\"><button onclick=\"submitComment(".$iPid."); return false;\">Post comment</button></td></tr>
        </table>
    </form>
        <div><span id=\"commentspsn\"></span>
        <div id=\"comments_list\">".$sComments."</div>
        </div>";

        $imageInfo = '';

     $selecT = "SELECT imagesrc FROM imagerate WHERE ImageSN ='".$iPid."'";
    $table = mysql_query($selecT);


    while($query = mysql_fetch_array($table))
    {
        $imageInfo.=$query['imagesrc'];
        }


   require_once('classes/Services_JSON.php');
    $oJson = new Services_JSON();
    header('Content-Type:text/javascript');
    echo $oJson->encode(array(
        'data1' => '<img class="fileUnitSpacer" src="uploads/'. $imageInfo.'">' . $sPrevBtn . $sNextBtn ,
        'data2' => $sCommentsBlock,
        'data3' => $sharewarning,

    ));
exit;
}

单击图像查看图像时显示

edit_album.php 直到它工作正常，但当我成功插入评论时，我想刷新评论以显示我被击中的新评论

用于处理注释和插入注释的jquery代码位于

之下 
function submitComment(id) {
    var sName = $('#name').val();
    var sText = $('#text').val();

    if (sName && sText) {
        $.post('acceptcomment.php', { action: 'accept_comment', name: sName, text: sText, id: id }, 
           function(data){ 

                    if (data != '1') {
                        $('#comments_list').fadeOut(2000, function () { 

                       $(this).html(data);

                        $(this).fadeIn(1000); 
    });

                       $("#commentspsn").html('<span id="commentspan"> <b>comment Submitted</b></span>');


                    } 

            }
        ); 
    } else {
        $('#comments_warning1').fadeIn(1000, function () { 
            $(this).fadeOut(1000); 
        }); 
    }
};

acceptcomment.php代码是

  $iItemId =(int)$_POST['id']; // prepare necessary information
        $sIp = getVisitorIP();
        $sName = $_POST['name'];
        $sText = $_POST['text'];

        if ($sName && $sText) {

            $sql = "SELECT ImageSN FROM comment_table  WHERE  ImageSN = '".$iItemId."' AND commentip = '".$sIp."' AND C_when >= 'UNIX_TIMESTAMP()-600' LIMIT 1";
            $query = mysql_query($sql);
          $array = mysql_num_rows($query);



            if ($array == 0 ) {
                $insert = "INSERT INTO comment_table SET ImageSN = '".$iItemId."' , commentip = '".$sIp."' , C_when = UNIX_TIMESTAMP(), c_name = '".$sName."', c_text ='".$sText."'";
                $sql = mysql_query($insert);

               $update= 'UPDATE imagerate SET comment_counts = comment_counts + 1  WHERE ImageSN = "'.$iItemId.'"';
                $query = mysql_query($update);                


               }  
                }
                    return 1;

修改你的accept comment.php以返回json响应，如下面的代码。

// prepare necessary information
$iItemId =(int)$_POST['id'];
$sIp = getVisitorIP();
$sName = $_POST['name'];
$sText = $_POST['text'];
$oJson = new Services_JSON();
if ($sName && $sText) {

    $sql = "SELECT ImageSN FROM comment_table  WHERE  ImageSN = '".$iItemId."' AND commentip = '".$sIp."' AND C_when >= 'UNIX_TIMESTAMP()-600' LIMIT 1";
    $query = mysql_query($sql);
    $array = mysql_num_rows($query);

    if ($array == 0 ) {
        $insert = "INSERT INTO comment_table SET ImageSN = '".$iItemId."' , commentip = '".$sIp."' , C_when = UNIX_TIMESTAMP(), c_name = '".$sName."', c_text ='".$sText."'";
        $sql = mysql_query($insert);

       $update= 'UPDATE imagerate SET comment_counts = comment_counts + 1  WHERE ImageSN = "'.$iItemId.'"';
       $query = mysql_query($update);  


       $data = array("item_id"=>$iItemId,"name"=>$sName,"text"=>$sText);
       return $oJson->encode($data);
    }  
}

return $oJson->encode(array("error"=>"Error while updating the comment"));

在您的Javascript代码中，使用收到的文本更新评论部分

function submitComment(id) {
    var sName = $('#name').val();
    var sText = $('#text').val();

    if (sName && sText) {
        $.post('acceptcomment.php', { action: 'accept_comment', name: sName, text: sText, id: id }, 
           function(data){ 

                if (!data.error) {
                    $('#comments_list').fadeOut(2000, function () { 

                        $(this).html(data.text);

                        $(this).fadeIn(1000); 
                   });

                   $("#commentspsn").html('<span id="commentspan"> <b>comment Submitted</b></span>');
                } 
            }
        ); 
    } else {
        $('#comments_warning1').fadeIn(1000, function () { 
            $(this).fadeOut(1000); 
        }); 
    }
};
