php - JavaScript - How do I execute certain query from dropdown select? -

-



i'd simplify code execute query based on user choose

the idea user show query based on base + group query when visit page first time. next, can decide data they'd see dropdown below

  //base   $material = "select material, count(material) 'total' `khitable` ";   $storagelocation = "select sloc ,count(sloc) 'total' `khitable`";   $verifstock = "select verif_stock ,count(verif_stock) 'total' `khitable`";    //tipe pipa   $erw = "where material '%er%'";   $sp = "where material '%sp%'";   $acc = "where material '%acc%'";    //status pengerjaan   $fg = "and material not '%sf-%'";   $wip = "and material '%sf-%'";    //ketersediaan   $so = "and so_number not '%605%'";   $buffer = "and so_number '%605%'";   $fs = "and material '%-fs%";    //group   $groupmaterial = "group material";   $groupsloc = "group sloc";   $groupverifstock = "group verif_stock";

and next user able choose data show dropdown list below 

<div class="row">   <div class="input-field col s4">           <select class="validate">       <option value="" disabled selected>pilih pilihan anda</option>       <option value="1">finish good</option>       <option value="2">semi finish (wip)</option>     </select>     <label >pilih berdasarkan status pengerjaan</label>   </div>   <div class="input-field col s4">           <select class="validate">       <option value="" disabled selected>pilih pilihan anda</option>       <option value="1">sales order</option>       <option value="2">buffer</option>       <option value="3">free stock</option>     </select>     <label >pilih berdasarkan status ketersediaan</label>   </div> </div>

so there 2 dropdown, , user see based on been choose on dropdown list. don't understand yet on code. here.

p.s. : data suppose viewed database, based on query shown

php:

//base  $select["material"] = "select material, count(material) 'total' `khitable` ";  $select["storagelocation"] = "select sloc ,count(sloc) 'total' `khitable`";  $select["verifstock"] = "select verif_stock ,count(verif_stock) 'total' `khitable`";   //tipe pipa $where["erw"] = "where material '%er%'"; $where["sp"] = "where material '%sp%'"; $where["acc"] = "where material '%acc%'";  //status pengerjaan $and1["fg"] = "and material not '%sf-%'"; $and1["wip"] = "and material '%sf-%'";  //ketersediaan $and2["so"] = "and so_number not '%605%'"; $and2["buffer"] = "and so_number '%605%'"; $and2["fs"] = "and material '%-fs%";  //group $group["groupmaterial"] = "group material"; $group["groupsloc"] = "group sloc"; $group["groupverifstock"] = "group verif_stock";  $query = $select[$_get["query_select"]]." ".          $where[$_get["query_where"]]." ".$and1[$_get["query_and1"]].          " ".$and1[$_get["query_and2"]]." ".$group[$_get["query_group"]];

html:

<form action="yourscript.php" method="get"> <!-- here form elements material,storagelocation etc -->   ................. <div class="row">   <div class="input-field col s4">           <select class="validate" name="query_and1">       <option value="" disabled selected>pilih pilihan anda</option>       <option value="fg">finish good</option>       <option value="wip">semi finish (wip)</option>     </select>     <label >pilih berdasarkan status pengerjaan</label>   </div>   <div class="input-field col s4">           <select class="validate" name="query_and2">       <option value="" disabled selected>pilih pilihan anda</option>       <option value="so">sales order</option>       <option value="buffer">buffer</option>       <option value="fs">free stock</option>     </select>     <label >pilih berdasarkan status ketersediaan</label>   </div> </div>  ............  </form>
