PHP update several rows in MySQL with one submit -


i have mysql database split 3 tables (tblmaincircles, tblsmallcircles, tbltabs) , php file updates data within these tables.

tblmaincircles:

mcid | mcname ------------- m1   | m1name m2   | m2name m3   | m3name ...  | ...

tblsmallcircles:

scid | scvisibleid | scvisible | mcid |scname ------------------------------------------------ m1s1 | m1s1v       | visible   | m1   | m1s1name m1s2 | m1s2v       | visible   | m1   | m1s2name m1s3 | m1s3v       | hidden    | m1   | m2s1 | m2s1v       | visible   | m2   | m2s1name ...  | ...         | ...       | ...  | ...

tbltabs:

tabid  | scid | mcid | tabname    | taburlid  | taburl ------------------------------------------------------------- m1s1t1 | m1s1 | m1   | m1s1t1name | m1s1t1url | m1s1t1urlname m1s1t2 | m1s1 | m1   | m1s1t2name | m1s1t2url | m1s1t2urlname m1s2t1 | m1s2 | m1   | m1s2t1name | m1s2t1url | m1s2t1urlname ...    | ...  | ...  | ...        | ...       | ...

my php form shows of current values user includes information 3 tables , multiple rows tblsmallcircles , tbltabs. shortened version of form looks this:

    <body>     <form action="<?php echo $_server['php_self']; ?>" method="post">         <ul>             <li>                 <label class="mctext">main circle:</label>                 <input type="text" class="textfield" id="mc" name="mc" value="<?php echo htmlspecialchars($m1); ?>"/>             </li>             <ul>                 <li class="sctext">                     <img src="images/triangle_right.png" alt="none" class="tri" id="sc1tri">                     <label>small circle 1:</label>                     <input type="text" class="textfield" id="sc1" name="sc1" value="<?php echo htmlspecialchars($m1s1); ?>"/>                 </li>                 <ul>                     <div class="doit">                     <li>                         <label class="tabtext">tab 1:</label>                         <input type="text" class="textfield" id="sc1t1" name="sc1t1" value="<?php echo htmlspecialchars($m1s1t1); ?>"/>                     </li>                     <li>                         <label class="urltext">tab 1 url/file:</label>                         <input type="text" class="textfield" id="sc1t1url" name="sc1t1url" value="<?php echo htmlspecialchars($m1s1t1url); ?>"/>                     </li>                     <li>                         <label class="pdftext">tab 1 pdf:</label>                         <input type="button" class="button" id="sc1t1pdf" name="sc1t1pdf" value="view" onclick="openm1s1t1url()"/>                         <span>          </span>                         <input type="file" name="sc1t1pdfup" id="sc1t1pdfup"/>                     </li>                     <li>                         <label class="tabtext">tab 2:</label>                         <input type="text" class="textfield" id="sc1t2" name="sc1t2" value="<?php echo htmlspecialchars($m1s1t2); ?>"/>                     </li>                     <li>                         <label class="urltext">tab 2 url/file:</label>                         <input type="text" class="textfield" id="sc1t2url" name="sc1t2url" value="<?php echo htmlspecialchars($m1s1t2url); ?>"/>                     </li>                     <li>                         <label class="pdftext">tab 2 pdf:</label>                         <input type="button" class="button" id="sc1t2pdf" name="sc1t2pdf" value="view" onclick="openm1s1t2url()"/>                         <span>          </span>                         <input type="file" name="sc1t2pdfup" id="sc1t2pdfup"/>                     </li>                     <li class="lipsace"></li>                     </div>                     <li>                         <input type="submit"  class="button" name='submit' value="submit"/>                         <span>          </span>                         <input type="button"  class="button" name='cancel' value="cancel" onclick="history.go(0)"/>                     </li>                 </ul>             </ul>         </ul>     </form> </body>

here sql update statements:

$usqlmc = "update tblmaincircles set mcname= '".$_post['mcname']."' mcid=???;";  $usqlsc = "update tblsmallcircles set scvisible= '".$_post['scvisible']."', scname= '".$_post['scname']."' scid=???;";  $usqlt = "update tbltabs set mcname= '".$_post['mcname']."' tabid=???;";

i stuck should place in ??? mcid= because varies based on fields have been complted.

hopefully provided enough information , not either! assistance great. new php , mysql comments welcome. in advance!

update

here updated lines of code have made. changed mcnames fields input value instead of m1.

html

<input type="text" class="textfield" id="mcname" name="mcname" value="<?php echo htmlspecialchars($m1); ?>"/>

sql

$usqlmc = "update tblmaincircles set mcname= '".$_post['mcname']."' mcid in ('m1','m2','m3','m4','m5');";

my goal have m1 updated have other inputs m2, m3, etc. on same form may need updated @ same time. there way without writing individual sql m1, m2, etc.

i can achieve writing 5 separate sql statements this:

$usqlm1 = "update tblmaincircles set mcname= '".$_post['mcnamem1']."' mcid='m1';"; $usqlm2 = "update tblmaincircles set mcname= '".$_post['mcnamem2']."' mcid='m2';"; $usqlm3 = "update tblmaincircles set mcname= '".$_post['mcnamem3']."' mcid='m3';"; $usqlm4 = "update tblmaincircles set mcname= '".$_post['mcnamem4']."' mcid='m4';"; $usqlm5 = "update tblmaincircles set mcname= '".$_post['mcnamem5']."' mcid='m5';";

but prefer 1 if possible.

mysql has 'in' syntax if updating several rows same property, can this: 

$usqlmc = "update tblmaincircles set mcname= '".$_post['mcname']."' mcid in ('m1', 'm2');";
