Getting More Numbers Into A Variable

[thara]

I am using a form to take a four digits length number from user..also users can enter more than one number by separating by commas in form's text field. My problem is if it is one number in text field its no problem to me and I can get it to php. but if there are more numbers I cant get those in to php. so anybody can help me to do this?

 

thank you very much.

Your code here.

I would think you could use the explode function using the comma as a seperator.

I can't see people inputing info in a form right each and every time. I think you'll also need something to remove spaces and a way to deal with numbers that are more or less than four charactors.

[thara]

this is my form...

 

 <form class="search_code" method="post"  action="">	 
  <input type="radio"  name="searchCode" class="searchRadio"  value="1" <?php if (isset( $searchCode) && $searchCode == 'TutorCode' ) echo "checked"; ?> /> Tutor (LITI)    
  <input type="radio"  name="searchCode" class="searchRadio" value="2" <?php if (isset( $searchCode) && $searchCode == 'InstituteCode' ) echo "checked"; ?> /> Center (LICI)	 
  <input type="text"  name="searchText" class="searchText" value="<?php if (isset( $searchText)) echo $searchText; ?>" />	  
  <input type="submit"  value="Go" class="searchGo" />
  <input type="hidden"  value="TRUE"  name="code_search_submitted" />
  <p>Enter Member Code <span style="color:red;">(s)</span> separated by comma</p>	  
 </form>

Do you have any code for processing the form?

 

 

 

As floridaflatlander suggested, you should be able to break apart the member code(s) with explode():

http://php.net/manua...ion.explode.php

 

The array returned by the explode() function can then be processed with a foreach loop. Within the loop, you'll want to remove any leading/trailing space with trim():

http://us3.php.net/m...nction.trim.php

 

...and check to make sure the member codes are numbers and are four digits or less. If any member code doesn't meet the criteria, send them back to the form and have the user fix the error(s).

Or, via a RegExp to avoid having to trim every element:

$RegExp = '/(\\d+)[,\s]*/';
preg_match_all ($RegExp, $data, $matches);
$numbers = $matches[1];

[thara]

this is the code for form processing that I have been trying so far..

 

//------------ Check code search bar form submission ---------------//
if ( isset( $_POST['code_search_submitted'])) {
if ( isset( $_POST['searchCode']) && !empty( $_POST['searchText'])) {   
 $searchCode = $_POST['searchCode'];
 $searchText = $_POST['searchText'];  
 if (is_numeric( $searchText ) && (strlen($searchText) == 4)) {

  if ( $searchCode == 1 ) {
   $_SESSION['searchCode'] = 'TutorCode';
  } elseif ( $searchCode == 2 ) {
   $_SESSION['searchCode'] = 'InstituteCode';  
  }

  $_SESSION['searchText'] = $searchText;

  $url = BASE_URL . 'search/searching.php'; // Define the URL:   
  ob_end_clean(); // Delete the buffer.
  header("Location: $url");
  exit(); // Quit the script. 

 } else {
  $searchingError= 'Enter four digits length number!';
  echo '<script type="text/javascript">';
  echo "alert('" . $searchingError . "')";
  echo "</script>";  
 }
} else {
 $searchingError= 'Enter Tutor or Institute Code!';
 echo '<script type="text/javascript">';
 echo "alert('" . $searchingError . "')";
 echo "</script>"; 
}
} //---- Check code search bar form submission ----//

I get a solution to this using 'explode()' something like this..

 

$numbers = explode(",", $searchText);
foreach($numbers as $number) {
$numbers =  trim($number);
}

 

I think now I need to check and make sure user given member codes are numbers and are four digits or less and there are more member codes etc.. so far I tried like this..

 

[/font][/color]
[color=#282828][font=helvetica, arial, sans-serif] if (is_numeric( $searchText ) && (strlen($searchText) == 4)) {[/font][/color]

[color=#282828][font=helvetica, arial, sans-serif] }

 

it is ok when one member code given... but I want to check with one or more member codes...

 

any idea?

 

Thank you.

Note that is_numeric() will accept values like "1e4" and "9.1". My current preference for checking numbers is ctype_digit():

http://www.php.net/m...ctype-digit.php

 

 

Does the number have to be four digits? Could "0322" be entered as "322"?

I modified the code for form processing something like this...

 

if ( isset( $_POST['code_search_submitted'])) {
if ( isset( $_POST['searchCode']) && !empty( $_POST['searchText'])) {   
 $searchCode = $_POST['searchCode'];
 $searchText = $_POST['searchText'];  [/font][/color]


[color=#282828][font=helvetica, arial, sans-serif]  echo $searchCode;
 echo '<br />';
 echo $searchText;
 //if (is_numeric( $searchText ) && (strlen($searchText) == 4)) {

 $numbers = explode(",", $searchText);
 foreach($numbers as $number) {
  $numbers =  trim($number);


  if (ctype_digit($numbers) && (strlen($numbers) == 4)) { 

   echo '<br />' . $numbers ;

  } else {

   echo 'Can not cantain string and more than 4 digists number';
  }

 }
   }
}

I tested it now and working.. but error message acting differently if user enter code in text field something like this... Eg: 1234,03443,23432,2344

 

Its output like this:

1234

Can not cantain string and more than 4 digists number

Can not cantain string and more than 4 digists number

2344

 

can anybody tell me what I need to do here?

Isn't that what you want? "03443" and "23432" are both 5-digit numbers which don't meet your criteria.

[thara]

yes... just think a user enter some values like this '34534,4535,34243,eew3,3243 etc... I need to display one error message.. telling strings are not accepting and more than four digits numbers also not accepting.. so how to check this?

 

Thank you.

Rather than echoing, turn that section of code into a function. When you get to an error, return the string. Then echo that one string. 

[cyberRobot]

If an error is found, is there any reason to continue processing the numbers? If not, you could end the foreach loop with break:

http://php.net/manua...tures.break.php

 

The break would go into the else portion with the error message.

[thara]

ok thanks.. I echoed $numbers for test.. Now I modified it like this..

 

if (ctype_digit($numbers) && (strlen($numbers) == 4)) { 

       $code[] =  $numbers ;
       $_SESSION['code'] = $code;

  } else {

       echo 'Can not cantain string and more than 4 digists number';
  }

 

Now I need to attach this $code value to a query. in WHERE clause.

 

this is my query..:

 

SELECT 
   tcs.tutor_id AS tid, 
   t.qualification,
   GROUP_CONCAT( DISTINCT o.option_name SEPARATOR ', ') AS tutor_option, 
   timg.image_name AS img, 
   city_name AS city,
   d.district_name AS district
FROM tutor_category_subject as tcs
   INNER JOIN subject AS s ON tcs.subject_id = s.subject_id
   INNER JOIN tutors AS t ON tcs.tutor_id = t.tutor_id
   INNER JOIN address ON address.address_id = t.address_id
   INNER JOIN city ON city.city_id = address.city_id
   INNER JOIN district AS d ON d.district_id = city.district_id
   LEFT JOIN tutor_images AS timg ON timg.tutor_id = tcs.tutor_id AND timg.image_type = 'profile'
WHERE t.tutor_code = ------------
GROUP BY tcs.tutor_id;

 

so please can you tell me how can I do this?

 

Thank you..
