seach MySQL data then update

uwictech · October 7, 2009

Hi all,

First of all, I am a complete novice, but I’m trying my best.

I have a data base with 6 fields, id, equ, ext, udf, udf2, udf3. I have created a web site that does various things like swap values, create new values, delete and search values.

I'm struggling with searching for a particular value then editing fields and updating it. I hope that makes sense?

Below is my code, I hope you can help.

You're going to need to be more specific

Sorry,

Basically, I can search for information and display the results into input boxes. I would then like to maniplulate that data and click an update button to update the database.

Here is the code I currently have:-

_{<div class="boxextupdate">}

_{<h3> Ext Update </h3>}

_{<form name="form5" method="post" action="../index1.php?page=tele">}

_{<p> Input Ext: <input type="number" name="ext" size="1" maxlength="4"/></p><br>}

_{<p> Ext: <input type="number" name="extupdate" value="<?php echo $extupdate; ?>" size="1" maxlength="4"/></p>}

_{<p> EQU: <input type="number" name="equupdate" value="<?php echo $equupdate; ?>" size="8" maxlength="20"/></p>}

_{<p> UDF: <input type="number" name="udfupdate" value="<?php echo $udfupdate; ?>" size="1" maxlength="4"/></p>}

_{<p> UDF2: <input type="number" name="udf2update" value="<?php echo $udf2update; ?>" size="1" maxlength="4"/></p>}

_{<p> UDF3: <input type="number" name="udf3update" value="<?php echo $udf3update; ?> " size="1" maxlength="4"/></p>}

_{<p> id: <input type="number" name="id" value="<?php echo $id; ?> " size="1" maxlength="4"/></p>}

_{<p><input type="submit" name="search" value="SEARCH"/></p>}

_{<p><input type="submit" name="update" value="UPDATE"/></p>}

_<?php

_{//update ext}

_{if ($_POST['search'])}

_{

_{$ext_formupdate = $_POST['ext'];}

_{$extract = mysql_query ("SELECT * FROM cy_equ WHERE ext='$ext_formupdate'");}

_{$numrows = mysql_num_rows ($extract);}

_{while ($row = mysql_fetch_assoc($extract))}

_{

_{$id = $row['id'];}

_{$equupdate = $row['equ'];}

_{$extupdate = $row['ext'];}

_{$udfupdate = $row['udf'];}

_{$udf2update = $row['udf2'];}

_{$udf3update = $row['udf3'];}

_}

_{if ($_POST['update'])}

_{

_{$sql = "UPDATE 'cy_equ' SET 'equ' = $_POST[equupdate], 'ext' = $_POST[extupdate], 'udf' = $_POST[udfupdate], 'udf2' = $_POST[udfupdate2], 'udf3' = $_POST[udfupdate3] 'id' = $_POST[id] WHERE id ='$_POST[id]'";}

_{mysql_query($sql) or die(mysql_error());}

_}

_?>
