PHP - Check If Exist

Code: [Select]
$arr = array('../', 'j/', 'AcidBB/', 'fileBOMB/', 'OurHome', 'up');
foreach ($arr as $value) {
    // echo "Value: $value<br /><br />";
if (is_dir($value)) {
echo "<tr> <td>{$value}</td> <td><font color='#66FF33'>Exists</font></td></tr><br />";
} else {
echo "<tr> <td>{$value}</td> <td><font color='#FF0000'>Does Not Exist</font></td></tr><br />";
}
}
~~~ Solved after posting. Sorry. ~~~
Ok i have an Array of directories i need to check before the script installs itself, I know how to check for directories but i dont know how to scan each array in the list without calling each one seperately in Code: [Select]
If() { } Else If { } Else If { } And so on and so on... My Question is, If a For Statement is neaded, How would i go about checking each string in the Array List?

//database
create table mydata (
	id int(11) NOT NULL PRIMARY KEY AUTO_INCREMENT,
	fname varchar(20),	
    phoneno int(12) NOT NULL

//class my data php

<?php

include('connect.php');
class InsertMydata {
    public function insertnow($fname, $phoneno) {
        $connect = new Connect;
        $insrt = $db -> prepare('INSERT INTO mydata (fname, phoneno) VALUES (?,?)');
		$insrt -> execute(array($fname, $phoneno));		
	}
}
?>


//insernow validate form

<?php
include('../classs/mydata.php');
//Declare data and error arrays
$errors = [];
$mydara = [];
if(!preg_match('/^[a-zA-Z]{4,15}$/', $_POST['fname'])) {
	$errors['fname'] = 'Enter full name!';
}
//this block not working even the phone exist
$connect = new Connect;
$phoneno = $_POST['phoneno'];
$checkiexist = $connect -> prepare('SELECT * FROM mydata WHERE phoneno = ?');
$checkiexist -> execute([$phoneno]);
if($checkiexist->rowCount() > 0) {
      $errors['phonenoexist'] = 'Try another phone number!';
 }
if(!empty($errors)){
      $data['success'] = false;
      $data['errors'] = $errors;
}else{
      $data['success'] = true;
      $data['message'] = 'success message!';  
      $mydata = new InsertMydata;
      $mydata -> insertnow($fname, $phoneno);
}
echo json_encode($data);

?>

//my ajax

$("#insertbtn").click( function(e) {
     var fname = $('#fname').val(),
         phoneno = $('#phoneno').val(),
           
       $.ajax({

           type: 'POST',
           data: {fname:fname, phoneno:phoneno},
           dataType: "JSON",
           encode: true,
        }).done( function (data) {
         
         if (data.success == false) {

                 $('#fname').append('<p class="text-danger">' + data.errors.fname + '</p>');
            } 
            if (data.errors.phonenoexist) {
              $('.card-header').append('<div class="alert alert-info alert-dismissible" role="alert">

As the title says, how can i check if multiple arrays exist inside an array or not?

Any help is greatly appreciated!

 

I have a customer registration form up and running, the form allows customers to complete the forms and the data is then inserted into mysql db table via php form. I want to prevent duplicates records from already existing customers from creating a new records instead I want the customers to update their existing records in the backend. That is allow them to complete the form as normal, once they hit the submit button, the code should check if the customer first name and last name is already in the database if yes then it should update their records and if not it should insert new record to the table.

 I do not want to alert the customer that their records already exist. I do not know where to start. Please help

 Thank you so much in advance for your help.

i have error where my code should update existing data where id exist, it get updated ..but the others data is disappeared .only the data updated is remained 

$sql1 ="select*from semakan_dokumen where email='$stdEmail'";
$sqlsearch1 = mysqli_query($dbconfig,$sql1);
$resultcount1 = mysqli_num_rows($sqlsearch1);

if($resultcount1 > 0){
$query1=("UPDATE  semakan_dokumen set student_id='$noMatrik', email= '$stdEmail', surat_tawaran='$fileName', ic='$fileName1',sijil_lahir='$fileName2',sijil_spm= '$fileName3',sijil_sekolah= '$fileName4', sijil_dip= '$fileName5',sej_julai='$fileName6',bm_julai='$fileName7',muet='$fileName8', mid1='$fileName9',yuran= '$fileName10',umpa_bend1= '$fileName11',umpa_bend2='$fileName12',bpkp='$fileName13', penaja='$fileName14',kesihatan= '$fileName15', jhepa='$fileName16' where email= '$stdEmail' ");

}else{


//filezip
$query1 = "INSERT INTO semakan_dokumen (email,surat_tawaran,ic,sijil_lahir,sijil_spm,sijil_sekolah,sijil_dip,sej_julai,bm_julai,muet,mid1,yuran,umpa_bend1,umpa_bend2,bpkp,penaja,kesihatan,jhepa) VALUES ('$stdEmail','$fileName','$fileName1','$fileName2','$fileName3','$fileName4','$fileName5','$fileName6','$fileName7','$fileName8','$fileName9','$fileName10','$fileName11','$fileName12','$fileName13','$fileName14','$fileName15','$fileName16')";
}

 

i wanting users to be able to update there email address and check to see if the new email already exists. if the email is the same as current email ignore the check.
i have no errors showing up but if I enter a email already in the db it still accepts the new email instead of bringing the back the error message.
Code: [Select]
// email enterd from form //
$email=$_POST['email'];


$queryuser=mysql_query("SELECT * FROM members WHERE inv='$ivn' ") or die (mysql_error());
 while($info = mysql_fetch_array( $queryuser )) {
  $check=$info['email'];
 // gets current email //
}


if($check!=$email){
// if check not equal to $email check the new email address already exists//
$queryuser=mysql_query("SELECT * FROM members WHERE email='$email' ");
//$result=mysql_query($sql);
$checkuser=mysql_num_rows($queryuser);
if($checkuser != 0)
{
$error= "0";
header('LOCATION:../pages/myprofile.php?id='.$error.'');


}
}

cheers

if so how would they be used in a mysql query?

hello, i am having an issue with tables using incorrect data.

i have 2 columns, first is employee name, second is location

if the employee doesnt have a location for the current day, it is telling me he is at the same location as the guy in the row above him.  i need this to be blank.  is this possible?

Hi all,

I want to make a script that identifies if an image JPG file exists.

Would somthing like this work?


<?php
$file = "images/image.jpg";
if ($file > 0) {
echo "file exists";
}
else { echo "no file"; }
?>

hi, i have a select which gets todays schedule for each user.  sometimes that user doesnt have anything for todays date and it will display the info from the user above him.  how can i make it so it stays blank if there is no record?

Basically this gets a number from a table on my DB, and displays the content relevent to that number...the second part checks for that number and gets other information according to that number...

what i want to do is make sure that the number from the first query exists in the table from the query, and if it doesn't print out and error saying "there is no information" or whatever..

anyone have an idea?

hopefully this makes sense

Code: [Select]
<?php
require_once('Connections/myConnect.php');
$detnum = $_GET['Details'];
$detinfo = mysql_query("SELECT* FROM `Agency Stores - Table 1` WHERE F11=".$detnum);
$det = mysql_fetch_array($detinfo);


$salesnum = $det['F3'];
$salesinfo = mysql_query("SELECT* FROM `By Agency Store _` WHERE store_store=".$salesnum);
$sales = mysql_fetch_array($salesinfo);

if(mysql_query("SELECT* FROM `By Agency Store _` WHERE store_store=".$salesnum)){

}

?>

hi,

im having trouble adding a get variable to a url if one already exists.

eg

current url = http://www.example.com/index.php?var1=something

i want to be able to change this to

new url = http://www.example.com/index.php?var1=something&var2=another

even so i can have a few get variable there.

I can add the first var through a form or link, but how would i add more through a link or through the header function?

I am positivly stuck.

Thanks

Does the concept of a "Namespace" exist in PHP?

If so, how do you use them?

This is a snippet from ASP.NET that made me ask this question...

Quote

<%@ Import Namespace="System.Data" %>
<%@ Import Namespace="System.Data.SqlClient" %>

Hi all -

I have a form that let's a user upload an image to their specified folder. The folder is determined by the "password" the user inputs. The "password" is really just the folder name on my server, so if "michael83" was entered as a password, the directory would be "images/uploaded/michael83". That works great now, thanks to a forum user, litebearer. Thanks again.

Here's my second question:

I'm working on a "history" page so that a user can input their "password" and view their upload history.

The form works right now. If you enter a "password" (folder name) that exists, the code will spit out the contents / files. So, now I'm looking for two things:

(1) if a user enters a "password" (folder name) that exists, but there are no files in the folder, "There are no files in the $dir directory." will be echoed; and

(2) if a "password" (folder name) is entered that does NOT exist, "The directory $dir does not exist." will be echoed.

Here's my code so far (minus the if statements I'm looking for):



$dir = $_POST['password'];
$path = "images/uploaded/". $dir;
$dir_handle = @opendir($path);

while ($file = readdir($dir_handle)) {
if($file == "." || $file == ".." )
continue;
if(isset($_POST['Submit']))

$url = "http://www.mysite.com/". $path . "/" . $file;
{
echo "<a href=\"$url\">$url</a><br />"; 
}}

closedir($dir_handle);



As always, many thanks in advance for any help on this.

Working with authorize.net script that is included in my php.  Trying to figure out how to use a variable beyond the 'case' I can do just about anything... inside the case... But I need to use the variable outside of there.

Code: [Select]
//several cases above
case 5:
$this->approval_code = $pstr_trimmed;
break;

// case 7 is the authorize.net transaction ID - This is the one I want to work with
case 7:
echo "Transaction ID: ";
echo $pstr_trimmed;
$trans_id_test = $pstr_trimmed;

break;
// but this below won't work. I can't use the variable anywhere outside of the case.
echo "the new variable is now...".$trans_id_test;
