php - $_post Problem (How to pass the value of $_post) -

-

i have following code works well.

the code display data database in input text field format. user able edit , update details clicking update button @ end of each row update specific row.

instead of clicking update buttons 1 one (if user wants edit , update more 1 row), create hyperlink update data @ once.

the problem dunno how pass value of $_post "update.php" since have

<form name="form1" action="submitaction.php" method="post">

i not sure possible so. or there other alternative ways?

<html> <script language="javascript" > <!-- hide function submitrequest(id) { document.forms[id].submit(); } // end hide --> </script>  <!-- javasript (onclick) remove readonly attribute--> <script language="javascript">   function removealignment(id){    document.getelementbyid("projectname_"+id).removeattribute("readonly",0);    document.getelementbyid("devicetype_"+id).removeattribute("readonly",0);   } </script>  <body> <?php  $counter=1; //connecting , accessing database  $con = mysql_connect("localhost","root",""); if (!$con)   {   die('could not connect: ' . mysql_error());   }  mysql_select_db("project", $con);  $result = mysql_query("select * project status='ongoing'");  ?>  <p><h2 align="center">adc project funnel</h2></p> <table border="1" bordercolor="lavender" cellspacing="0" cellpadding="0">   <tr>     <td width="20" bgcolor="steelblue" height="15" style="font-size: 11" align="center"><b><font face="arial">no</font></b></td>     <td width="78" bgcolor="steelblue" height="15" style="font-size: 11" align="center"><b><font face="arial">project       name</font></b></td>     <td width="72" bgcolor="steelblue" height="15" style="font-size: 11" align="center"><b><font face="arial">device type</font></b></td>     <td width="67" bgcolor="steelblue" height="15" style="font-size: 11" align="center"><b><font face="arial">status</font></b></td>     <td width="67" bgcolor="steelblue" height="15" style="font-size: 11" align="center"><b><font face="arial"></font></b></td>   </tr>   <tr>   <td colspan="15" height="15" bgcolor="#afeeee"><font face="arial" size="1.9">current project assignment</font></td>   </tr>    <!-- records database (current project assignment) -->   <?php    $i = 0;     while ($row=mysql_fetch_array($result)){   ?>     <tr>     <form name="form1" action="submitaction.php" method="post">     <td height="5" width="20"  align="center" style="font-size: 13" valign="middle"><?php echo $counter; ?></td>     <td height="5" width="72" ><input type="text" autocomplete=off readonly="readonly" id="projectname_<?php echo $i; ?>" name="projectname<?php echo $row['no'];?>" value="<?php echo  $row['projectname'];?>" size="20" style="font-size: 10"></font></td>     <td height="5" width="72" ><input type="text" autocomplete=off readonly="readonly" id="devicetype_<?php echo $i; ?>" name="devicetype<?php echo $row['no'];?>" value="<?php echo  $row['devicetype'];?>" size="15" style="font-size: 10"></font></td>     <td height="5" width="67" style="font-size: 13">     <select name="action" onchange="submitrequest(<?php echo $i; ?>);">     <option value=>ongoing </option>     <option value="<?php echo $row['projectname'];?>">complete</option>     <option value="<?php echo $row['flag2'];?>">future</option>     <option value="<?php echo $row['flag1'];?>">cancel</option>     <option value="<?php echo $row['no'];?>">update</option>     <option value="<?php echo $row['flag3'];?>">delete</option>     </select>                                        </td>     <td height="5" width="64" ><input type="button" style="width:100%" value="edit" onclick="removealignment(<?php echo $i; ?>);"></td>     </tr>     </form>      <?php       ?>    <?php    $i++;   $counter++;   }   ?>        <tr>   <td colspan="16" bgcolor="#afeeee"><font face="arial" size="1.9">add new project assignment</font></td>   </tr>     <!-- add new records -->   <tr>    <form action="project_insert.php" method="post">      <td width="20" ></td>      <td width="78" ><input type="text" autocomplete=off name="projectname"  size="40" style="font-size: 10"></font></td>      <td width="72" ><input type="text" autocomplete=off name="devicetype" size="15" style="font-size: 10"></font>      <td width="80" style="font-size: 13">          <select name="status" style="width:100%">             <option value=future>future</option>             <option value=ongoing>ongoing</option>                  </select>              </td>        <td>         <input type="submit" style="width:100%"value="add">         </td>      </form>   </tr> </table> <br/>  <table border="0" align="center" cellpadding="0" cellspacing="10">     <tr>          <td valign="middle"><a href="http://localhost/project/update.php">update</a></td>    </tr> </table>  <br/> </body> </html>

make 1 form tag - not individual form tag each row.

next change:

<select name="action" onchange="submitrequest(<?php echo $i; ?>);">

to:

<select name="action[<php echo $i; ?>]" onchange="submitrequest(<?php echo $i; ?>);">

(it's better use primary key database instead of $i counter, don't is.)

also has not been necessary do:

<!-- hide // end hide -->

for 10 years already, should stop including that.

actionscript 3 - TweenLite does not work with object -

-
i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines. ...
