I am building a small web interface for MySQL database using PHP. One task is to allow users to be able to input a string into a text field and the system should return the name of any table that contains this string in its name. However, my problem is that, every time you enter in the web interface, it will by default display all the table names. Here is my complete code.
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
</head>
<style>
.error {color: #FF0000;}
</style>
<body>
<h1>This is H1</h1>
<?php
$servername = "xxx";
$username = "xxx";
$password = xxx;
// Create connection
$conn = new mysqli($servername, $username, $password);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
?>
<?php
$search = $searchErr = "";
if ($_SERVER["REQUEST_METHOD"] == "POST") {
if (empty($_POST["search"])) {
$searchErr = "Search keyword is required";
} else {
$search = test_input($_POST["search"]);
if (!preg_match("/^[a-zA-Z ]*$/",$name)) {
$nameErr = "Only letters and white space allowed";}
}
}
function test_input($data) {
$data = trim($data);
$data = stripslashes($data);
$data = htmlspecialchars($data);
return $data;
}
?>
<h2>Search Keyword</h2>
<p><span class="error">* required field.</span></p>
<form method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>">
Search: <input type="text" name="search" value="<?php echo $search;?>">
<span class="error">* <?php echo $searchErr;?></span>
<br><br>
<input type="submit" name="submit" value="Submit"> </form>
<?php
echo '<h2> Search Result: </h2>';
$searchSQL = "SELECT table_name FROM information_schema.tables
WHERE LOWER(table_name) LIKE LOWER('%$search%')
AND table_schema = 'xxx'";
$result = $conn->query($searchSQL);
echo '<form method="POST" action="show_columns.php">'; // opening form tag
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
$table_name = $row['table_name'];
echo "<input type='submit' name='table_name' value='$table_name' /> <br/>";
}
} else {
echo ' ';
}
echo '</form>'; // closing form tag
?>
</body>
</html>
For example, every time I enter the web end, the search result will display all the table names. I assume that it might take empty string as the search key word? Any ideas on how to get around with it? Thanks in advance!
This might not be the cleanest solution, but I add a condition before executing the search queries
if ($search!='')
{$result = $conn->query($searchSQL);}
else {...}
...
and the problem is solved. Thanks for all your suggestions.

hi i found a code on internet and edited a bit but i stuck on showing the correct result i want.. when i type the email address i get the correct result but if i have more than 1 entry i always get the last one is it possible to make it show the result based on the email and the date?
here is my code so far
<?php
// php search data in mysql database using PDO`enter code here`
// set data in input text
$id = "";
$reservation_name = "";
$persons = "";
$date = "";
$time = "";
$email = "";
$status= "";
if(isset($_POST['Find']))
{
// connect to mysql
try {
$pdoConnect = new PDO("mysql:host=localhost;dbname=multi_edit","root","");
} catch (PDOException $exc) {
echo $exc->getMessage();
exit();
}
// id to search
$email = $_POST['email'];
// mysql search query
$pdoQuery = "SELECT * FROM member WHERE email = :email";
$pdoResult = $pdoConnect->prepare($pdoQuery);
//set your id to the query id
$pdoExec = $pdoResult->execute(array(":email"=>$email));
if($pdoExec)
{
// if id exist
// show data in inputs

I have work out what you need, it require email (like foobar#gmail.com) and date (like 2018-09-23) in the form input field, if you submit it return the Reservation Name.
Notice for simplicity reason I removed these 3 columns "persons", "time" and "status", but you can add it back, it doesn't change the logic because the finding/query don't need those fields for input
This is my code:
<?php
// php search data in mysql database using PDO`enter code here`
// set data in input text
function sqlInitConn ($args) {
// Initialze connection.
$serverName = $args["serverName"];
$userName = $args["userName"];
$password = $args["password"];
$dbName = $args["dbName"];
$conn = new PDO("mysql:host=$serverName;dbname=$dbName", $userName, $password, array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8"));
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
return $conn;
}
// Those variables are for input to mysql.
$idIpt = "";
$reservation_nameIpt = "";
$emailIpt = "";
$dateIpt = "";
// Those variables are for output to front-end.
$idOpt = "";
$reservation_nameOpt = "";
$emailOpt = "";
$dateOpt = "";
if(isset($_POST['find']))
{
try {
// Connect to mysql.
$pdoConnect = sqlInitConn([
"serverName" => "localhost",
// Change it to your server name.
"userName" => "root",
"password" => "change_it_to__your_password_here_if_your_mysql_need_password",
"dbName" => "multi_edit",
]);
} catch (PDOException $exc) {
echo $exc->getMessage();
exit();
}
$emailIpt = $_POST['email'];
$dateIpt = $_POST['date'];
$pdoQuery = "SELECT * FROM member WHERE email = :email AND date = :date";
// Mysql search query
$pdoResult = $pdoConnect->prepare($pdoQuery);
$pdoResult->bindValue(":email", $emailIpt);
$pdoResult->bindValue(":date", $dateIpt);
$pdoExec = $pdoResult->execute();
if($pdoExec) {
// If record exist, show data in inputs
if($pdoResult->rowCount() > 0) {
foreach($pdoResult as $row) {
$idOpt = $row['id'];
$reservation_nameOpt = $row['reservation_name'];
$emailOpt = $row['email'];
$dateOpt = $row['date'];
break;
// only get first occurrences (get first matching record) to prevent corrupted data
// , because same email might wrongly log twice in same day (= same date), like morning and afternoon.).
}
}
else {
echo 'No Reservation Found On This Email';
// If the id not exist, show a message and clear inputs
}
} else {
echo 'ERROR Something Is Wrong Try Again';

I want to have a form with php. but for many hours I'm involved an error and the error is when $_POST=['name'] wants to be checked empty or not it is empty.
When I check the database the row is white and nothing is there.
for checking if the $_POST is empty or not I print word 'empty' to be determined it's empty and it will be printed 'empty';
where is my mistake is it related to database mysql or not just in code?
please help me I got confused and bored.
this is whole of my codes:
<!doctype html>

} else {

$name = test_input($_POST["name"]);
// check if name only contains letters and whitespace

thank you in advance
The problem is in use of empty()
You can use it on variables not on values.
See here for PHP documentation page.
To check this, first save it in another variable and then check:
$tempVal = $_POST["name"];
if (empty($tempVal))
you can use this simple example
<?php
if(isset($_POST['submit']))
{
$name = $_POST['name'];
echo "User Has submitted the form and entered this name : <b> $name </b>";
echo "<br>You can use the following form again to enter a new name.";
}
?>
<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<input type="text" name="name"><br>
<input type="submit" name="submit" value="Submit Form"><br>
</form>
i suggest this:
Understanding $_SERVER['PHP_SELF']
I am new to PHP coding. I have created two forms. One is for signing up and the other for logging in. Unfortunately both fail to work due to some issues in the queries. I also searched and went through similar posts on this site but none solved my problem. I want to verify whether a user with the same id exists in the database "Users.db" at the time of signing up if any user enters the same id he should be notified to enter a valid id.
When I run my "sign in.php" code, it displays the following message on the screen without even waiting for the user to press the submit button/ sign up button.. "Number of rows found: 1 .This id is not available. Please enter a valid id." This message gets displayed even if the user enters a unique id that doesnt exist in the database before. Nothing gets stored in my database even if the id is unique by pressing the sign up button.
Secondly while logging in, the id and password entered by the user must be verified and matched with those stored in the database. He should be directed to the "index.html" page after successfully login in and only if he has signed up before. He should also be able to view his search history that is stored in "Search" table in the same database. This table contains two columns. One for the User id and the other for saving his search results.
The Search table looks like:
Id | History

Please guide me as i am stuck in both these codes.
What you are missing is checking if $_POST is set or is not empty. Only then you want to process user input. One more thing is that you should wrap $pass in quotes as it is a string and will be interpreted as column name if not surrounded with quotes.
Here's code:
log in.php
<!DOCTYPE HTML>
<html>
<head>
<style>
.error {color: #FF0000;}
label{display:inline-block;width:100px;margin-bottom:10px;}
</style>
</head>
<body>

$pass=null;

Please see my code below.
How can I return the control to the index.php to an executable statement after the closing form tag to display query results on index.php page rather than code shown toward the end of processData.php?
I have searched through Google, this forum and have not seen a solution? Those familiar with Fortran, Visual Basic would appreciate the return statement that can be used to go back to the calling routine. Is there a statement similar to return to hand over the control to the calling web page in PHP?

If I take your question literaly this is one possibility:
In processData.php put that link where ever you want it to be:
back to index.php
then you can react on that parameter in index.php:
....
<input type="submit" value="Submit">
</form>
//Question - How to return the control to a statement after </form> tag to print values instead of processData.php**
<?php
if(isset($_GET['state'])) {
switch($_GET['state']) {
case "fromProcess":
echo "I come from process!";
// do whatever you want to do
break;
default:
echo "ERROR: undefined state submitted";
}
}
?>
</body>
</html>
There's of course also the possibility to redirect without clicking a link via
header("location: index.php?state=fromProcess");
// NOTE: This has to be before ANY output, and no output after that will be seen.
But I have the feeling, that you actually want to display data generated from processData in index.html.
Then you got at least two possibilities:
Include processData.php in index.php and wrap it in a
<?php
if(isset($_POST['author_name'])) {
include('processData.php');
// process the data and make output
}
?>
Same is possible the other way round (but that's kinda tricky for what you want to do).
One general thing you have to keep in mind:
php scripts are scripts, basicly all on their own.
They are out of memory once they finished executing, so you cannot call a function of another script unless you include it into the current script (without autoload - but that not what you want).
I am creating a form to connect to a database using PHP. I have the form semi-functional but when I'm trying to test it by pressing the submit button, it says file not found on the webpage.

I am new to this language and still learning.
Any help or advice would be greatly appreciated.
Thank you
What version of PHP you are using to run this script?
As I can see you are using "Register globals" setting to get $_POST data: http://php.net/manual/en/security.globals.php
If you have PHP version 5.4+ you should use $_POST['form_field_name1'] ... $_POST['form_field_nameN'] to get form data.
Add check:
if (!empty($_POST)) { /* Form validation data goes here */ }
File is incorrect, the form action url points to default.php but your filename is defaul.php
Make if default.php instead of defaul.php
For better handling:
In console of your browser, please check the http call, you can see the error it is showing if its a 500 (check logs / enable the debug mode)
