Insertion of data into Database

Question

//Connection.php

<?php
$host = 'localhost';
$user = 'root';
$password = '';
$db = 'faculty_corner';

$link = mysqli_init();
$success = mysqli_real_connect( $link, $host, $user, $password, $db);

if ($success == TRUE) {
    echo 'KUDOS !!! Connected to Database';
} 
?>

//varpay.php (the page from where I want the data to be sent to db)

//insert statement: in this form I have put fid as an autoincrement and calculation = NULL as I have a view button there which lets me to go to next page 'p1.php'

<pre>
<?php

if ($_POST['submit'] == 1){

$sql = "INSERT INTO `faculty_corner`.`tabdata` (fid, `facname`, `designation`, basic, varper, varamt, appamt, calculation) VALUES (NULL, '$_POST[facname]', '$_POST[designation]', $_POST[basic], $_POST[varper], $_POST[varamt], $_POST[appamt], NULL)";

if(mysqli_query($success, $sql)){
    echo "Records added successfully.";
} else{
    echo "ERROR: Could not able to execute $sql. " . mysqli_error($link);
}

// Close connection
mysqli_close($link);

}

?>
</pre>

<form action="varpay.php" method="post">
<table name="myTable">
  <thead>
    <tr>
      <th style="border-top-left-radius:10px;">S.no</th>
      <th>Faculty Name</th>
      <th>Designation</th>
      <th>Basic AMt.</th>
      <th>Var %</th>

    </tr>
  </thead>
  <tbody>
    <tr>
      <td align="center" style="width:60px;" name="fid">1</td>
      <td><input name="facname" type="text" class="boxin" type="number"/></td>
      <td align="center" style="width:60px;" ><input type="text" name="designation" class="boxin"/></td>
      <td align="center"><input name="basic" class="boxin" type="number"/></td>
      <td align="center"><input name="varper" class="boxon" type="number"/></td>      
      <td align="center"><input name="varamt" class="boxin" type="number" value="" /></td>
      <td align="center"><input name="appamt" class="boxin" type="number" value="" /></td>
      <td align="center"><a href="p1.php"><input type="button" name="calculation" value="view"/></a></td>
    </tr>

    <tr><td colspan="8" align="center"><button type="submit" name="submit"> SUBMIT </button></td></tr>

  </tbody>
</table>
</form>

This is my error.

Answer 1

首先，如果是自动增量列，则无需提及fid。其次，你与使用＆＃39;不一致。 尝试使用此版本替换查询：

$sql = "INSERT INTO `faculty_corner`.`tabdata` (facname, designation, basic, varper, varamt, appamt) VALUES ('$_POST[facname]', '$_POST[designation]', '$_POST[basic]', '$_POST[varper]', '$_POST[varamt]', '$_POST[appamt]')";

Answer 2

将所有帖子值// First #include <original set of templates and specializations> // Next // Define new specialization. // Then #include <class that uses the specialization, possibly from another assembly> // Finally // Code that uses the #include'ed class that uses the specialization. 更改为$_POST[SomeName]。您在$_POST['SomeName']内缺少'。

对于自动增量，只需在数据库表中将square bracket []更改为column fid和primary key即可。它会自动增加。

我已更新了我的代码。请看看。
