Question

我无法获得价值目标

if (isset($_POST['Register'])) {
     $indexRegValue = $_POST['RegValue']; // value from index page e.g 490
     echo '$indexRegValue';
     $ipValue = "490";
     $lfvalue = 790;
     $spvalue = 990;
     if ($ip == $indexRegValue) {
         $titlevalue = "490";
     } else if ($lfvalue === $indexRegValue) {
         $title = "790";
     } else if ($spvalue === $indexRegValue) {
         $titlevalue = "990";
     }
}
echo $titlevalue; // value to print

Answer 1

    if (isset($_POST['Register'])) {
    $indexRegValue = $_POST['RegValue']; // value from index page e.g 490
    echo '$indexRegValue';
    $ipValue = "490";
    $lfvalue = 790;
    $spvalue = 990;
    if ($ipValue == $indexRegValue) {      // corrected variable
       $titlevalue = "490";
                                 } 
    else if ($lfvalue == $indexRegValue) {  
     $titlevalue = "790";          // Corrected variable
                                     } 
   else if ($spvalue == $indexRegValue) {   //changes
     $titlevalue = "990";
                                     }
                           }
   echo $titlevalue; // value to print

您要检查和打印的变量中有错字

Answer 2

您在$ip中输入错了，而不是od $ipValue

if (isset($_POST['Register'])) {
     $indexRegValue = $_POST['RegValue']; // value from index page e.g 490
     echo '$indexRegValue';
     $ipValue = "490";
     $lfvalue = 790;
     $spvalue = 990;
     if ($ipValue == $indexRegValue) {// your typo mistake
         $titlevalue = "490";
     } else if ($lfvalue == $indexRegValue) {//changes
         $titlevalue = "790";// your typo mistake
     } else if ($spvalue == $indexRegValue) {//changes
         $titlevalue = "990";
     }
}
echo $titlevalue; // value to print
