在PHP中选择正确的数据

Question

我下面有一个界面

当我单击“编辑”按钮（图标铅笔）时，将出现以下表格

编辑按钮在php文件中具有以下代码：

$elisting ="";

    $queryf = "select employee.id as myid,jobtitle,info,locid,deptid,gender,dob,emid,employee$cid.name,username,dept,datejoin,location.name as loc from  employee

        left join location on location$cid.id = employee.locid 

        inner join department on department.id = employee.deptid order by username

    ";

    $resultf = pg_query($queryf); 

    $numrows = pg_numrows($resultf);

    while ($rowf = pg_fetch_array($resultf)) {

        $ct=$ct+1;

        $myid = $rowf[myid];

        $uname = $rowf[username];

        $loc1 = $rowf[loc];

        $dept = $rowf[dept];

        $date = $rowf[datejoin];

        $name = $rowf[name];

        $emid = $rowf[emid];

        $dob = $rowf[dob];

        $gender = $rowf[gender];

        $job = $rowf[jobtitle];

        $info = $rowf[info];

        $datejoin = $rowf[datejoin];

        $locid = $rowf[locid];

        $deptid = $rowf[deptid];

        $newbal = $rowf[newbal];

        $templatelist = "";

        $tempcn = 0;

        $querytemp = "select tid,ltype from leaveatemplate$cid where username='$uname' order by tid desc";

        $resulttemp = pg_query($querytemp); 

        while ($rowtemp = pg_fetch_array($resulttemp)) {

            $tempcn = $tempcn +1;

            $tid = $rowtemp[tid];

            $ltype = $rowtemp[ltype];

            if($tempcn=="1")

                $templatelist = "$ltype|$tid";

            else

                $templatelist = $templatelist.","."$ltype|$tid";

        }

        $elisting=$elisting."<tr><td align=\"center\">$uname</td><td align=\"center\">$loc1</td><td align=\"center\">$dept</td><td align=\"center\">$date</td><td align=\"center\"><button class=\"btn btn-mini\"data-toggle=\"modal\"href=\"#long\"
onClick=\"javascript:edit('$name','$uname','$emid','$dob','$gender','$job','$info','$datejoin','$locid','$deptid','$myid','$templatelist', '$value');\"><i class=\"icon-pencil\"></i></a><button class=\"btn btn-mini\" data-toggle=\"modal\" href=\"#static\" rel=\"tooltip\"  data-original-title=\"Delete\" onClick=\"javascript:delrec('$myid');\"><i class=\"icon-remove\"></i></a></td>
        </tr>\n";
        }

我不知道在单击按钮时代码如何选择正确的数据？ 因为我看到查询中没有要求，例如id = 123或类似的东西。 选择adam时，将显示adam的数据。 有人可以解释吗？

更新：

function edit(a,b,c,d,e,f,g,h,i,j,k,l){
        document.getElementById("frm").id.value=k;
      document.getElementById("frm").name.value=a;
      document.getElementById("frm").username.value=b;
      document.getElementById("frm").emid.value=c;
      document.getElementById("frm").dob.value=d;
      setCheckedValue(document.forms['frm'].elements['gender'],e);
      document.getElementById("frm").job.value=f;
      document.getElementById("frm").info.value=g;
      document.getElementById("frm").datejoin.value=h;
      document.getElementById('locid').value=i;
      document.getElementById('deptid').value=j;
}

Answer 1

此行说明了所有内容：

onClick=\"javascript:edit('$name','$uname','$emid','$dob','$gender','$job','$info','$datejoin','$locid','$deptid','$myid','$templatelist', '$value');

如您所见，在javascript编辑功能中，对象的ID（我猜是$myid ）与对象的所有其他属性一起传递。
