<?php defined('c5_execute') or die("access denied.");  ?> <div class="ccm-ui"><?php   $db= loader::db(); //this loads database helper. loader::model('user'); //this loads user model. $u = new user(); $ui = userinfo::getbyid($u->getuserid()); //this gets user info current user.  $usercostcenter =  $ui->getattribute('cost_center'); //this sets variable equal attribute cost center current user.  //the if statement below checks if user admin , displays info accordingly. if($usercostcenter == "admin"){ ?>       <form name="selectcostcenter" action="/adminorder" method="post">         <select name="costcenter">             <option value="unitedilluminating">united illumination</option>             <option value="clp">cl&p</option>         </select>         <input type="submit" value="continue"<button style="float:right;" type="button" class="btn btn-primary"></button>      </form>        <?php     }elseif($usercostcenter == "united illuminating"){   ?> <form name="orderform" action="/confirm" method="post">     <?php $query = 'select * vendors costcenterid = 1';         $productquery = 'select * products costcenterid =  1'; $results = $db->getall($query); $productresults = $db->getall($productquery);?>  <table class="table">               <thead>                 <tr>                   <th>quantity/product</th>                   <th>category</th>                   <th>vendor</th>                   <th>address</th>                 </tr>  <?php  foreach ($results $vendor) { ?> <tr class="category">     <td></td>     <td><?php echo $vendor['category'];?></td>     <td><?php echo $vendor['vendor'];?> </td>     <td><?php echo $vendor['address'];?></td>      </tr>      <?php   foreach ($productresults $product){     ?>        <tr class="product">     <td colspan="4"><span class="name"><input type="text" name="quantities[]" size="1" /><?php echo $product['product'];?></span></td>     </tr>     <?php  }     ?>     <td><input type="hidden" name="vendor[]" value="<?php echo $vendor['vendorid']; ?>"/></td>         <?php    }?>  </table> <input type="submit" value="checkout"<button style="float:right;" type="button" class="btn btn-primary"></button> </form> </div><?php }  else {     ?> <form name="orderform" action="/confirm" method="post">     <?php $query = 'select * vendors costcenterid = 2';         $productquery = 'select * products costcenterid =  2'; $results = $db->getall($query); $productresults = $db->getall($productquery);?>  <table class="table">               <thead>                 <tr>                   <th>quantity/product</th>                   <th>category</th>                   <th>vendor</th>                   <th>address</th>                 </tr> <?php  foreach ($results $vendor) { ?> <tr class="category">     <td></td>     <td><?php echo $vendor['category'];?></td>     <td><?php echo $vendor['vendor'];?> </td>     <td><?php echo $vendor['address'];?></td>      </tr>      <?php   foreach ($productresults $product){     ?>        <tr class="product">     <td colspan="4"><span class="name"><input type="text" name="quantities[<?php echo $vendor['vendorid']; ?>]" size="1" /><?php echo $product['product'];?></span></td>     <td><input type="hidden" name="vendor[]" value="<?php echo $vendor['vendorid']; ?>"/></td>     </tr>         <?php  }     ?>    <?php    }?>  </table> <input type="submit" value="checkout"<button style="float:right;" type="button" class="btn btn-primary"></button> </form> </div><?php }  ?>

this confirm page below.

<?php defined('c5_execute') or die("access denied."); $db= loader::db(); $quantity = $_post['quantities']; $vendor = $_post['vendor']; $minimumorder = 25;  foreach($quantity $num){     if ($num >= $minimumorder){         echo "$num";         echo "</br>";         foreach($vendor $vendors){             echo "$vendors";             echo "</br>";         }     } }    ?>

i appreciate can give. has had me stumped few days actually.

you might want rearrange array, , like:

$i = 0; foreach ($productresults $product) {      echo '<input name="product['.$i.'][quantity]" />';      echo '<input name="product['.$i.'][vendor_id]" value="'.$vendor['vendorid'].'" type="hidden" />';      ++$i; }

the resulting array in $_post have quantities & vendor separated own arrays.

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
