I have a PHP script that outputs my events from my ICAgenda calendar on the website.
It outputs "name" "date" and "location" / event.
How can I import this into XCODE to show the events?
I thought styling the php script, and then add it as a webview in XCODE ? Or I'll guess there is another workaround to get the data in XCODE ?
This is the code that gathers the events:
<?php
$servername = "myservername";
$username = "username";
$password = "password";
$dbname = "dbname";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT next, title, city FROM jos_icagenda_events ORDER BY next";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo "Datum & tijd: " . $row["next"]. "<br>";
echo "Plaats: " . $row["title"]. "<br>";
echo "Locatie: " . $row["city"]. "<br><br>";
}
} else {
echo "0 results";
}
$conn->close();
?>

The below code I got from the w3 schools website and adapted it a little to my db but no matter what when I click on my search button I only get the first line printed and nothing else. It doesn't even print if the connection to my db is successfully made or not.
I used chrome's dev tool to check my network traffic and I can see my POST request made successfully:
name: bahamas
submit: Search
I enabled logging for both error and general on my mysql instance, and did a grep for bahamas and got no hits. So this would seem to indicate that the script didn't even query my db?
IE this is what I get: https://imgur.com/a/PHKBmbU
<?php echo("PHP Search Page Loaded Successfully");
if(isset($_POST['submit'])){
if(preg_match("^/[A-Za-z]+/", $_POST['name'])){
$servername = "localhost";
$username = "test";
$password = "test";
$dbname = "test";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
} else {
echo("We are not dead");
}
$sql = "SELECT boatname, date, price FROM liveaboards";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo("<br> boatname: ". $row["boatname"]. " - date: ". $row["date"]. " " . $row["price"] . "<br>");
}
} else {
echo(" 0 results");
}
$conn->close();
}
}else{
echo("<p>Please enter a search query</p>");
}
?>
In following the theme of W3 Schools (one of my favorite resources), here is the correct way to sanitize data: https://www.w3schools.com/php/php_filter.asp
Applied to your code:
<?php echo("PHP Search Page Loaded Successfully");
// test variables.
$_POST['submit'] = true;
$_POST['name'] = "bahamas";
if(isset($_POST['submit'])){
$_POST['name'] = filter_var($_POST['name'], FILTER_SANITIZE_STRING);
$servername = "localhost";
$username = "test";
$password = "test";
$dbname = "test";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
} else {
echo("We are not dead");
}
$sql = "SELECT boatname, date, price FROM liveaboards";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo("<br> boatname: ". $row["boatname"]. " - date: ". $row["date"]. " " . $row["price"] . "<br>");
}
} else {
echo(" 0 results");
}
$conn->close();
}else{
echo("<p>Please enter a search query</p>");
}
?>
According to your POST result, you are receiving name: bahamas submit: Search , if so then Correct this
if(isset($_POST['submit'])){
TO
if(isset($_POST['Search'])){
What I wan't to do is create buttons that are automatically generated from the database. So when I add a new record in the database the button is created Is this possible with a loop? So yes how do I create the button.
This is what I have so far:
<?php
$servername = "localhost";
$username = "root";
$password = "Iamthebest1009";
$dbname = "dktp";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT * FROM theme";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo "". $row["theme_name"]. "<br>";
}
} else {
echo "no results";
}
$conn->close();
?>
Yes it is possible. you need to echo html
<?php
$servername = "localhost";
$username = "root";
$password = "Iamthebest1009";
$dbname = "dktp";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT * FROM theme";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
$your_url ="https://www.google.com";
echo "". $row["theme_name"]. "<br>";
echo '<input type="button" name="' . $row["theme_name"]. '" value="'. $row["theme_name"].'">';
}
} else {
echo "no results";
}
$conn->close();
?>
I have a fairly simple PHP page which displays some fields from a database.
For some reason I get:
Notice: Undefined index: entries.id in /var/www/html/originalprices.php on line 24
I can't see whats wrong, could anyone help? Thanks
<?php
$servername = "localhost";
$username = "root";
$password = "password";
$dbname = "zxdb";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT entries.id, entries.title, entrytypes.text,entries.original_price, entries.budget_price,labels.name FROM entries,publishers, labels, entrytypes
where entries.entrytype_id = entrytypes.id
and publishers.entry_id = entries.id
and publishers.label_id = labels.id
and labels.id = '1371'";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo "id: " . $row["entries.id"]. " - Name: " . $row["entries.title"]. " " . $row["entrytypes.text"]. "<br>";
}
} else {
echo "0 results";
}
$conn->close();
?>
The Name of the returned field will be "id" not entries.id.
You can check that by using var_dump()
i am new to PHP, and i am attempting to create a simple connection from html to mySQL using php. I met with some problems when running my codes.
this is my code:
<?php
$servername = "localhost";
$username = "root";
$password = "password";
$dbname = "database";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT username FROM users";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo "<br> id: ". $row["userid"]. ;
}
} else {
echo "0 results";
}
$conn->close();
?>
after running on a browser, this is displayed:
connect_error) { die("Connection failed: " . $conn->connect_error); } $sql = "SELECT username FROM users"; $result = $conn->query($sql); if ($result->num_rows > 0) { // output data of each row while($row = $result->fetch_assoc()) { echo "
id: ". $row["userid"]. ; } } else { echo "0 results"; } $conn->close(); ?>
Do you have mysql running on your localhost machine? You must verify that it is working first before you can connect via php. Also, make sure you have TCP/IP sockets open in mysql and to make sure it isn't just listening via unix sockets.
echo "<br> id: ". $row["userid"]. ;
this is a syntax error, no need to end it with a full stop.also the correct syntax to connect to sql server is
mysqli_connect("localhost","my_user","my_password","my_db") or die("");
Debug the code before posting it here.
maybe try testing it with a try catch statement. Its what I've done. this way you can display your error messages a little more nicely. As for the cause, PressingOnAlways is probably right
If you are using wampserver or any other server you need to put your php files into c:\wamp\www folder and run them in browser by typing localhost/nameofyourfile.php (change c:\wapm\www for your server installation path or type)
you have the syntax error in blow line
echo "<br> id: ". $row["userid"]. ;
. (dot) should not be there.
second you fetch usernamestrong text by following query
$sql = "SELECT username FROM users";
but you try to get userid
echo "<br> id: ". $row["userid"]. ;
try below code.
<?php
$servername = "localhost";
$username = "root";
$password = "password";
$dbname = "databasename";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT usersname FROM users";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo "<br> id: ". $row["usersname"] ;
}
} else {
echo "0 results";
}
$conn->close();
?>
Currently I just done HTML and I trying writing PHP Script on connection Mysql, But all web site on google is confuse, because now I need specify write connection by used PHP Only,
Please could you help explain step by step on code from HTML to PHP and write PHP to MySql, Thank you very much.
There is many docs about this, but you can start from here:
http://www.w3schools.com/php/php_mysql_select.asp
And here is the example code, what i suggest you:
<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";
// Create connection
$conn = mysqli_connect($servername, $username, $password, $dbname);
// Check connection
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
$sql = "SELECT id, firstname, lastname FROM MyGuests";
$result = mysqli_query($conn, $sql);
if (mysqli_num_rows($result) > 0) {
// output data of each row
while($row = mysqli_fetch_assoc($result)) {
echo "id: " . $row["id"]. " - Name: " . $row["firstname"]. " " . $row["lastname"]. "<br>";
}
} else {
echo "0 results";
}
mysqli_close($conn);
?>
