php - Update echoed data using WHILE loop. Only updates one record -


i can't seem able update records except first one. not sure how modify of displayed records.

<?php      if(isset($_post["action"]) == "update")     {         $id = $_post['m_id'][0];         $type = $_post['type'][0];         // if echo $id & $type, gives me first record.**         mysql_query("           update membership_type           set mt_type ='$type'           mt_id = '$id'"         );     }       ?>

all of within same php page.

<form name=form action='' method='post'>    <?php    $result=mysql_query("select * membership_type;");   while($rows=mysql_fetch_array($result))   {  ?>     <input size=35 class=textfield type=text name='type[]' value='<?php echo  $rows['mt_type']; ?>'>     <input type=hidden name='m_id[]' value="<?php echo $rows['mt_id']; ?>">     <input type=submit value="update">   <?php    }    ?>

how edit of displayed records clicking update button???

first: should never use mysql_* functions deprecated.
second: try code:

<?php    // connection database $mysqli = new mysqli('host', 'user', 'password', 'database');  // check if there's post request in file if($_post){       foreach($_post['m_id'] $id => $type){       $query = "update membership_type                 set mt_type = '".$type."'                 mt_id = '".$id."'";        // try exec query       $mysqli->query($query) or die($mysqli->error);     } }else{     // membership_type records , iterate   $result = $mysqli->query("select * membership_type") or die($mysqli->error); ?>    <form name='form' action='<?php echo $_server['php_self'] ?>' method='post'>     <?php while($row = $result->fetch_object()){ ?>       <input size='35'               class='textfield'               type='text'               name='m_id[<?php echo $row->mt_id ?>]'               value='<?php echo $row->mt_type; ?>'>       <input type='submit' value="update">     <?php } ?>   </form>  <?php } ?>

third: in order add more security (this code vulnerable), try mysqli_prepare

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
