将参数传递给 PHP 表超链接

Question

我希望我的 php 表的第二列和第三列成为每行的不同页面的超链接。我需要将 3 个参数传递给超链接
1) 第一列的值 - empID 列在下表中
2) 来自 $weekStart 的值 - 从页面顶部的 input type="date" 中选择
3) 来自 $weekEnd 的值 - 从页面顶部的 input type="date" 中选择

我正在尝试这种语法，但它没有传入参数并且我收到一个找不到页面的错误。应如何更改此语法以传递所有 3 个参数并导航到适当的页面？

Week Start:<input type="date" name="weekStart">
Week End:<input type="date" name="weekEnd">
<input type="submit" name="submit" value="View Employee Data">

<?php
if (isset($_POST['submit'])) 
{
    $weekStart = $_POST['weekStart'];
    $weekEnd = $_POST['weekEnd'];

    //Generate Table Here
}
?>
foreach ($tsql as $res) 
{
    print "<tr>";
    print "<td>" . $res->EmpID . "</td>";
    print "<td><a href="DailySales.php?param1=$weekStart;param2=$weekEnd'.$Row['EmpID'].'">'.$Row['DailySales'].'</a>'" . $res->DailySales . "</td>";
    print "<td><a href="WeeklySales.php?param1=$weekStart;param2=$weekEnd'.$Row['EmpID'].'">'.$Row['SalesForWeek'].'</a>'" . $res->SalesForWeek . "</td>";
    print "</tr>";
}

Answer 1

你没有很好地附加字符串。请尝试以下代码

foreach ($tsql as $res) 
{
   print "<tr>";
   print "<td>" . $res->EmpID . "</td>";
   print "<td><a href='DailySales.php?param1=".$weekStart."&param2=".$weekEnd."&param3=".$Row['EmpID']."'>".$Row['DailySales']."</a>" . $res->DailySales . "</td>";
   print "<td><a href='WeeklySales.php?param1=".$weekStart."&param2=".$weekEnd."&param3=".$Row['EmpID']."'>".$Row['SalesForWeek']."</a>" . $res->SalesForWeek . "</td>";
   print "</tr>";
}

如果仍然显示未找到页面，请检查文件名。

更新：我希望您需要替换循环中的一些变量，如以下代码中更新的那样

foreach ($tsql as $res) 
{
   print "<tr>";
   print "<td>" . $res->EmpID . "</td>";
   print "<td><a href='DailySales.php?param1=".$weekStart."&param2=".$weekEnd."&param3=".$res->EmpID."'>".$res->DailySales."</a></td>";
   print "<td><a href='WeeklySales.php?param1=".$weekStart."&param2=".$weekEnd."&param3=".$res->EmpID."'>".$res->SalesForWeek."</a></td>";
   print "</tr>";
}

完全未经测试，我不能 100% 确定这些链接中的数据应该做什么，但我认为这应该给你一个坚实的起点，你可以调整 HTML 生成以获得你想要的。

我根本不会费心尝试在 PHP 中执行此操作，将整个数据集传递给 JS 并在那里执行。

Week Start:<input type="date" name="weekStart" id="weekStart">
Week End:<input type="date" name="weekEnd" id="weekEnd">
<input type="submit" name="submit" value="View Employee Data">

<?php
if (isset($_POST['submit'])) 
{
    $weekStart = $_POST['weekStart'];
    $weekEnd = $_POST['weekEnd'];

    //Generate Table Here
}

// Create a JSON version of your data to pass to the script
$data = json_encode( $tsql );
?>

<!-- Create an empty table for your data-->
<table id="employee-table"></table>

<script> 
$("#submitForm").on("click", function(e) {
  // Stop the form from reloading the page
  e.preventDefault();

  // Set up your variables, you'll need to add ID's to the form inputs
  var employees = <?php echo $data; ?>;
  // See the employees data in your inspector console
  console.log(employees);

  var weekStart = $("#weekStart").val();
  var weekEnd = $("#weekEnd").val();

  // Generate the HTML for all the employees
  var html = "";
  for( var1=0; i<employees.length; i++ ) {
    html += "<tr>";
    html += "<td>" . employees[i].EmpID . "</td>";
    html += "<td><a href='DailySales.php?param1='" + weekStart + "'&param2='" + weekEnd + "'&param3='" + employees[i].id +">"  + employees[i].DailySales + "</a></td>";
    html += "<td><a href='WeeklySales.php?param1='" + weekStart + "'&param2='" + weekEnd + "'&param3='" + employees[i].id +"'>" + employees[i].SalesForWeek + "</a></td>";
    html += "</tr>";
  }

  // Insert the HTML that you generated into the table.
  $("#employee-table").html(html);
});
</script>
