please check my script.
if($namachief != NULL)
{
echo $namachief;
}
else if ($namarm != NULL)
{
echo $namarm;
}
else
{
echo "Something wrong. Please contact US";
}
My condition isn't working when in this condition => $namarm != NULL, I only get white page but its normal when in this condition => $namachief != NULL.
It's fine when i do this
echo $namachief; & echo $namarm;
if () {
}
else if (){
}
else if(){

}
Both answer below are right. My problem lies here. In my form I did this
<option value="none">None</option> Then i change it to <option value="">None</option>
You try like this
if($namachief != NULL || $namachief != "")
{
echo $namachief;
}
else if ($namarm != NULL || $namarm != "")
{
echo $namarm;
}
else
{
echo "Something wrong. Please contact US";
}
Write your condition as below:-
if(isset($namachief) && !empty($namachief)){
echo $namachief;
}
else if (isset($namarm) && !empty($namarm)){
echo $namarm;
}
else{
echo "Something wrong. Please contact US";
}
If you want to print both variables if both are set and have valid values then,
if(empty($namarm) && empty($namachief)){
echo "Something wrong. Please contact US";
}
else if (!empty($namachief) && !empty($namarm)){
echo $namarm;
echo $namachief;
}
else if (isset($namarm) && !empty($namarm)){
echo $namarm;
}
else if(isset($namachief) && !empty($namachief)){
echo $namachief;
}
else{
// else stuff
}

I have this code I have set up that is supposed to read from JSON and output each array. Except when I use my foreach loop, I have an unreachable if statement. It's supposed to reach it if "type" is "rawbr".
I have confirmed that this has nothing to do with foreach by placing the same message in a row.
I wish to output this:
UnknownUser3: hey hxor? [To you]
Welcome to chat!
Here is my code:
innerchat.php:
<?php
session_start();
function tf($oz){
if($oz == 0){
return false;
} else if($oz == 1){
return true;
}
}
if(isset($_GET["room"]) && file_exists("data/".$_GET["room"].".json")){
$jsonF = file_get_contents("data/".$_GET["room"].".json");
$jsonD = json_decode($jsonF, true);
echo count($jsonD["msg"]);
// echo $jsonD["msg"][1]["type"];
foreach($jsonD["msg"] as $key => $message){
if($message["visibility"] !== "all"){
if(isset($_SESSION["ts_user"]) && $_SESSION["ts_user"] == $message["visibility"] && $message["type"] != "rawbr"){
echo "<font color='".$message["color"]."'><b><u>".$message["from"].":</u></b></font> ".htmlspecialchars($message["cont"])." [To you]<br />";
} else if($message["type"] === "message" && $message["visibility"] === "all"){
echo "<font color='".$message["color"]."'><b><u>".$message["from"].":</u></b></font> ".htmlspecialchars($message["cont"])." [normal message]<br />";
} else if($message["type"] === "rawbr" && $message["visibility"] === "all"){
echo $message["cont"]."<br />";
}
}
}
}
kb6k.json (the room we're working with)
{"name":"KillerBot 6000","desc":"A room with very harsh moderation. Proceed with caution!","max":600,"color":"#e0e0e0","whispersenabled":true,"forbiddenCommands":["/milk", "/bal"],"msg":[{"cont":"hey, hxor?","time":1,"color":"black","type":"message","visibility":"HxOr1337","from":"UnknownUser1"},{"cont":"Welcome to the chat!","time":0,"type":"message","color":"black","visibility":"HxOr1337","from":"Test"}]}
I know it couldn't possibly do anything to do with the JSON itself, since the other values are nearly identical apart from "visibility"
Ok, so I figured out that I put those if statements in $message["visibility"] !== "all"
The code:
<?php
session_start();
if(isset($_GET["room"]) && file_exists("data/".$_GET["room"].".json")){
$jsonF = file_get_contents("data/".$_GET["room"].".json");
$jsonD = json_decode($jsonF, true);
// echo $jsonD["msg"][1]["type"];
foreach($jsonD["msg"] as $key => $message){
if($message["visibility"] !== "all"){
if(isset($_SESSION["ts_user"]) && $_SESSION["ts_user"] == $message["visibility"] && $message["type"] != "rawbr"){
echo "<font color='".$message["color"]."'><b><u>".$message["from"].":</u></b></font> ".htmlspecialchars($message["cont"])." [To you]<br />";
}
} else {
if($message["type"] === "message" && $message["visibility"] === "all"){
echo "<font color='".$message["color"]."'><b><u>".$message["from"].":</u></b></font> ".htmlspecialchars($message["cont"])." [normal message]<br />";
} else if($message["type"] === "rawbr" && $message["visibility"] === "all"){
echo $message["cont"]."<br />";
}
}
}
}
I receive the information with this form correctly.
$findNIF = User::where('nif','=',$nif)->get();
$findEmail = User::where('email','=',$email)->get();
I need to compare if it is the same value the "nif" and "email" of the $findNIF and $findEmail.
$findNIF["0"]["nif"];
$findNIF["0"]["email"];
$findEmail["0"]["nif"];
$findEmail["0"]["email"];
I use the following sentence but I always receive "OK"
if ($findNIF["0"]["nif"] && $findNIF["0"]["email"] && $findEmail["0"]["nif"] && $findEmail["0"]["email"]){
echo "OK";
} else {
echo "NO";
}
Here
if ($findNIF["0"]["nif"] && $findNIF["0"]["email"] && $findEmail["0"]["nif"] && $findEmail["0"]["email"]){
echo "OK";
} else {
echo "NO";
}
in your condition if you get values in both of your $findNIF and $findEmail variables then it always return true.
If you want to compare the nif of $findNIF & $findEmail and email of $findNIF & $findEmail both then this would be like this
if (($findNIF["0"]["nif"] == $findEmail["0"]["nif"]) && ($findNIF["0"]["email"] == $findEmail["0"]["email"])){
echo "OK";
} else {
echo "NO";
}
Please elaborate more about what you need.
I'm trying to allow access for certain content only for specific member's user and administration.
With the following code I can't view the content when I'm logged as admin:
<?php
if (is_category(4)) {
if (!current_user_can('my-group') || !current_user_can('add_users')) {
echo '<h1 class="entry-title">You can not access</h1><p>This content is only for Administrator and group\'s members.</p>';
}
} else {
?>
Also I tryed each condition individually, but as admin I can't view the content.
I tryed this example code:
<?php if (is_category(8)) {
if (!current_user_can('mio-gruppo') || !user_can('administrator')) {
echo 'you can not pass';
}
} else {
echo 'you pass';
}
?>
But the two conditional statement goes in conflict. If I try both separately works right
I guess it should be && instead of ||:
<?php
if (is_category(4)) {
if (!current_user_can('my-group') && !current_user_can('add_users')) {
echo '<h1 class="entry-title">You can not access</h1><p>This content is only for Administrator and group\'s members.</p>';
}
} else {
?>
Alternatively make it the other way round:
<?php
if (is_category(4)) {
if (current_user_can('my-group') || current_user_can('add_users')) {
echo 'access granted';
} else {
echo 'no access';
}
}
?>
This is what I need:
<?php
if (is_category(8) && (current_user_can(array(1,2,3,4,5,6,7)) || !is_user_logged_in())) {
if (!current_user_can('mio-gruppo')) {
echo 'you can not pass';
}
} else {
echo ' you can pass';
}
?>
I have this if statment
if(!empty($URL) && ($safe===true)){
//lots of code
}
Is it possible to show different error messages depending on what condition failed?
For example if $URL is empty echo "URL empty";
and if $safe===false echo "GTFO";
Just add this to your code
else if(empty($URL)
{
echo "url empty";
}
else if($safe===false)
echo "Get Out"; // be polite ;)
if (empty($url))
{
echo "URL empty";
}
elseif ($safe === false)
{
echo "GTFO";
}
else
{
//lots of code
}
} else {
if($safe === false){
die("GTFO");
}
if (empty($url)){
echo "URL Empty.";
}
}
Yes; you could make use of an else if statement.
if (!empty($URL) && ($safe===true)) {
//lots of code
} else if (empty($URL)) {
// report that url is empty
} else if ($safe === false) {
// report that safe is false
}
Alternatively, you could just use an else statement to report that the if condition was false.
I propose the following solution. It will allow you to show multiple errors and set each condition only once (instead of having so many conditions and anti-conditions as other solutions proposed).
$errors = array();
if(empty($URL) {
$errors[] = 'URL empty';
}
if($safe !== true) {
$errors[] = 'GTFO';
}
if(empty($errors)) {
//lots of code
} else {
echo '<ul>';
foreach($errors as $error_message) {
echo '<li>' . $error_message . '</li>';
}
echo '</ul>';
}
How can I create a function in PHP that checks if a file input is selected? The following is what I have but its not working.
Thank you!
function mcFileUp($mcFile){
if(empty($_FILES[$mcFile]['name'])){
echo 'empty';
}
else{
echo 'Ok!';
}
}
I figured it out:
function mcFileUp($mcFile){
if(empty($mcFile))
{
echo 'empty';
}
else
{
echo 'Ok!';
}
}
mcFileUp($_FILES['mcFileUpload']['name']);
Here is a possible solution
function mcFileUp($mcFile)
{
if(strlen($_FILES[$mcFile]['name'])==0)
{
echo 'empty';
}
else
{
echo 'Ok!';
}
}
if(isset($_FILES["uploaded_file"]))
{
if((!empty($_FILES["uploaded_file"])) && ($_FILES['uploaded_file']['error'] == 0))
{
............
}
else
{
echo "Error: File ".$_FILES["uploaded_file"]["name"]." already exists";
}
}
else
{
echo "Error: No file uploaded";
}
