按钮 PHP HTML 的 Href

Question

嗨，我想在用户单击按钮后进行 href

这是我当前的代码，但它不起作用。 我点击后，确认会出来，但我点击后它不会进入PHadmin_approveHospital.php。

echo "<a href=\"PHadmin_approveHospital.php?id=".$row["HospitalID"]."\" onclick=\"return  confirm('do you want to approve Y/N')\"><input type=\"submit\" value=\"Approve\"></a>";

全功能

public function displayAllHospital() {
        $sql = "SELECT * FROM hospital";
        $result = @mysqli_query($this->conn, $sql);
        echo "<table class='table table-bordered'>";
        echo "<thead>";
        echo "<tr>";
        echo "<th>ID # <i class='fa fa-sort'></i></th>";
        echo "<th>Name </th>";
        echo "<th>Email </th>";
        echo "<th>Contact Number <i class='fa fa-sort'></i></th>";
        echo "<th>Status </th>";
        echo "<th>Actions</th>";
        echo "</tr>";
        echo "</thead>";
        echo "<tbody>";
        while($row = mysqli_fetch_assoc($result)){
            echo "<tr>";
            echo "<td>" . $row["HospitalID"] . "</td>";
            echo "<td>" . $row["Hospitalname"] . "</td>" ;
            echo "<td>" . $row["email"] . "</td>" ;
            echo "<td>" . $row["contactno"] . "</td>" ;
            echo "<td>" . $row["status"] . "</td>" ;
            echo "<td>";
            echo "<a href=\"PHadmin_editHospital.php?id=".$row["HospitalID"]."\" class='view' title='View' data-toggle='tooltip'><i class='material-icons'>&#xE417;</i></a>";

            echo "<a href=\"PHadmin_deleteHospital.php?id=".$row["HospitalID"]."\" onclick=\"return  confirm('do you want to delete Y/N')\" class='delete' title='Delete' data-toggle='tooltip'><i class='material-icons'>&#xE872;</i></a>";
            echo "</td>";
            echo "<td>";
            if($row["status"] == "pending"){
                echo "<a href=\"PHadmin_approveHospital.php?id=".$row["HospitalID"]."\" onclick=\"return  confirm('do you want to approve Y/N')\"><input type=\"submit\" value=\"Approve\"></a>";
            }
            echo "</td>";
            echo "</tr>";
            echo "</tbody>"; 
            echo "</form>";
            echo "</tr>";
        }
        echo "</table>";
    }

谢谢你的帮助。

您可以在点击按钮时调用一个javascript函数，然后显示确认信息，以便用户确认或不确认（如果确认，则跳转到url）

您可以使用以下代码：

<input type="button" value='Approve' onclick="javascript:check1();">

<script>
function check1() {
   if(confirm("Do you want to approve?"))  {
      window.location.href="PHadmin_approveHospital.php?id=<?php echo $row["HospitalID"]. '\'; ?>";
   }    
}
</script>

因此，对于您更新的代码，它将是：

<?php

public function displayAllHospital() {


echo '
<script> 
function check1(var1) {
   if(confirm("Sure to delete ?"))  {
      window.location.href="PHadmin_deleteHospital.php?id=" +var1;
   }    
}

function check2(var2) {
   if(confirm("Sure to approve ?"))  {
      window.location.href="PHadmin_approveHospital.php?id=" + var2;
   }    
}
</script>';




        $sql = "SELECT * FROM hospital";
        $result = @mysqli_query($this->conn, $sql);
        echo "<table class='table table-bordered'>";
        echo "<thead>";
        echo "<tr>";
        echo "<th>ID # <i class='fa fa-sort'></i></th>";
        echo "<th>Name </th>";
        echo "<th>Email </th>";
        echo "<th>Contact Number <i class='fa fa-sort'></i></th>";
        echo "<th>Status </th>";
        echo "<th>Actions</th>";
        echo "</tr>";
        echo "</thead>";
        echo "<tbody>";
        while($row = mysqli_fetch_assoc($result)){
            echo "<tr>";
            echo "<td>" . $row["HospitalID"] . "</td>";
            echo "<td>" . $row["Hospitalname"] . "</td>" ;
            echo "<td>" . $row["email"] . "</td>" ;
            echo "<td>" . $row["contactno"] . "</td>" ;
            echo "<td>" . $row["status"] . "</td>" ;
            echo "<td>";
            echo "<a href=\"PHadmin_editHospital.php?id=".$row["HospitalID"]."\" class='view' title='View' data-toggle='tooltip'><i class='material-icons'>&#xE417;</i></a>";
            echo "<a href=\"PHadmin_editHospital.php?id=".$row["HospitalID"]."\" class='edit' title='Edit' data-toggle='tooltip'><i class='material-icons'>&#xE254;</i></a>";
            echo "<input type=button value=Delete onclick='javascript:check1(". $row["HospitalID"]  . ")';>";

            echo "</td>";
            echo "<td>";
            if($row["status"] == "pending"){

            echo "<input type=button value=Approve onclick='javascript:check2(". $row["HospitalID"]  . ")';>";

            }

            echo "</td>";
            echo "</tr>";
            echo "</tbody>"; 
            echo "</form>";
            echo "</tr>";
        }
        echo "</table>";
    }
