PHP - Check Filename And Match To Variable

I was wondering if it is possible to check the content for a variable for a certain work.  For example say a variable called "$variable1" was equal to "one, two, three, four, five".  How can I check to see if the variable contain the word "four"?  Thanks for any help. 

i am pulling the login date from the databases and i want it to check if the variable is empty and if it is echo Never Loged In and if it not empty echo the date
          <?php
          include'db.php';
  $id=$_GET['id'];
  $sql=mysql_query("SELECT * FROM admin WHERE id='$id'")or die(mysql_error());
  while($row=mysql_fetch_array($sql))
  {
  $date=$row['login_date'];
  if($date > 0)
  {
  echo"Never Loged In";
  }
  else
  {
  echo"$date";
  }
  }
  ?>

 if ($d = opendir("uploads")) {
    while ($file = readdir($d)) {
      if ($file != "." && $file != ".."    )
   //  if( is_file($file) )
       {
        $files[] = $file;
      }
    }
    closedir($d);
  }

if ($file != "." && $file != ".."    $file !=  ????????  )   just a bit stuck here

$showCountSql      =   "select cad_count from counteraccountdtl WHERE cad_userid =".$_SESSION['UID']." LIMIT 1";
$showCountresult    =    mysql_query($showCountSql);
$showCountrow      =    mysql_fetch_array($showCountresult);
$newCount      =   $showCountrow[cad_count];


if(is_int($newCount))
 echo "Value  is Integer";
else
 echo "Value not Integer";


i m fetching value by Mysql "cad_count integer(5)" and  feild then i cheak this value is interger  or not it show the "Value not Integer". What is wrong in it ???

Hi,

How can I check if a variable only has these characters:
- number (0-9)
- decimal point (.)
- positive (+)
- negative (-)
- dollar ($)

I tried is_numeric, but it doesn't like negative values...

I need to add the variable value to another variable. I have to accept numbers (including negative and decimals)...

ex:
0.1 = TRUE
-.1 = TRUE
12 = TRUE
1000.00 = TRUE
12a = FALSE



thanks

I have the following if statement:

Code: [Select]
if ((isset($select_category) == 'All') || (!isset($select_category)) && (!isset($most_liked))) {

The value for the variable gets taken from a drop down menu, which is a list of categories.

The problem I am having is with the isset condition check is that the variable is always set, but it does not consider the check for equality with the 'All' condition. Which basically means no matter which category I choose from the drop down menu, it always goes to this very first if statement, and does NOT go to the other elseif statement, and I think it has to do with the isset condition check, because without it it would work, though without it I am getting a notice warning, that the variables are undefined.

Any ideas how I can make it check if its equal to 'All' together with the isset condition check?

What I am trying to say is no matter which category is chosen, with the isset condition check, the variable is always set, thus the if statement is true, there basically seems to be a contradiction going on.

Hey all,

Let's say I want to do something like this:

Code: [Select]
<?php
function exists($a){
$b ||= $a;
}

echo exists(1);
?>
Basically, every time exists is called, it will only assign b to a if b  isn't already initialized.

What's the most effective way to achieve the equivalent in php? ternary?

Thanks for response.

Code: [Select]
<?php

session_start(); 
$index="1";
$_SESSION[$index]=2;
echo "$_SESSION[$index]";

?>
Hi good day check how to have a variable "$index" inside session..

Hi,
I am struggling with a form in php. I am trying to add a form by using the include function. I want to include thsi form on all pages so it would be very useful if I can save the current page name somewhere so that I can use to validate the form.

For example, this is the form I am trying to include.

<?php
if(!empty($errors))
{
if(isset($errors['sendError']))
{
echo '<p><strong class="error">There was a problem with our system please contact us directly.</strong></p>';
}
else
{
echo '<p><strong class="error">Please check the form below for errors.</strong></p>';
}
}
?>
<form action="index.php" method="post" id="form1">
<p>
<label><?php if(isset($errors['name'])) { echo '<span class="error">'; } ?>Name<font color="red">*</font>: <?php if(isset($errors['name'])) { echo '</span>'; } ?></label>
<input id="search1" id="complete" type="text" value="<?php echo $form['name']; ?>" name="name" size="60" align="right" style="background:#EEF5A4" />

<label><?php if(isset($errors['company'])) { echo '<span class="error">'; } ?>Company: <?php if(isset($errors['company'])) { echo '</span>'; } ?></label>
<input id="search1" id="complete" type="text" value="<?php echo $form['company']; ?>" name="company" size="60" align="right" />

<label><?php if(isset($errors['phone'])) { echo '<span class="error">'; } ?>Phone Number: <?php if(isset($errors['phone'])) { echo '</span>'; } ?></label>
<input id="search1" id="complete" type="text" value="<?php echo $form['phone']; ?>" name="phone" size="60" align="right" />

<label><?php if(isset($errors['email'])) { echo '<span class="error">'; } ?>Email<font color="red">*</font>: <?php if(isset($errors['email'])) { echo '</span>'; } ?></label>
<input id="search1" id="complete" type="text" value="<?php echo $form['email']; ?>" name="email" size="60" align="right" style="background:#EEF5A4" />

<label><?php if(isset($errors['enquiry'])) { echo '<span class="error">'; } ?>Enquiry: <?php if(isset($errors['enquiry'])) { echo '</span>'; } ?></label>
<textarea id="search1" id="complete" textarea name="enquiry" rows=4 cols=40 value="<?php echo $form['enquiry']; ?>" name="enquiry" size="60" align="right"></textarea>
</p>
<p>
<input type="submit" class="formbutton" value="Submit" />&nbsp;<input type="reset" class="formbutton" value="Reset" />
</p>
<p><font color="red">*</font> Denotes a required field</p>
</form>

Because I am going to use this form on all pages, I would like it to include whatever the filename is rather than index.php in the first line of the form so that when the user clicks submit, it will stay on the same page but validate the form based on the mandatory fields.

I don't know if the question is clear. I would very much appreciate any help at all.

Thank you very much.

I want to validate my PHP files to ensure that I didn't forget to import all the classes assigned to attributes.  I will be using ReflectionClass to do so and need the FQCN's and not the filenames.  Originally, I tried get_declared_classes(), however, ran into issues where a class was already declared.  I came up with the following which appears to work, however, it was created based on trial and error and suspect there might be edge cases where it will not provide the desired results (and it is pretty damn ugly as well).  How would you recommend doing so?  A couple thoughts a

Use composer to come up with the classes based on filename and use either vendor/Composer autoload_classmap.php or autoload_static.php.  I don't really like this approach as it requires me to update composer to add any new files. Use composer but figure out how it generates the class map and use a similar approach.  Appears that it is using phpstan or some other utility but I haven't really investigated. Use some third party script to generate the class maps.  If so, please provide recommendations. Use some more modern approach other than PhpToken.  If so, please provide recommendations. Use get_declared_classes() to get a base line and then require the PHP file to find the added class names and somehow deal with issues related to classes already being declared. Use tokens and my parseFile() method.  If so, any recommendations on changing?

PS.  I originally wasn't 100% that attributes in traits and abstract classes would be propagated to the concrete class, but I should have known it to be true and this was confirmed by testing.  At this time, I really just need the concrete classes, however, maybe in the future I will use the script to do some analysis on interfaces, traits, etc.

I need to process a CSV file in database (MySql using LOAD DATA INFILE)), while the code is working fine but it works only with file that is already on my apache server (where php is installed).

Is there any way (Java/Ajax or anything) that I can prompt user to select a file from any loaction they prefer including there desktop??

Thanks in advance!!

Hi everyone.

I have a small problem.
I have a database that shows student images, in the format of 1234.jpg but the file name extension is in both upper case and lower case.
My server OS is linux ubuntu. apache2 php5.
Linux see these as 2 different file so will not show the upper case ones. 1234.JPG

What i have already is working but for lower case only, i need something to detect when the extension is in uppercase and change accordingly.

This is what i have now that works for lower case only.

<img src=../images/mbr_images/<?php echo H($mbr->getBarcodeNmbr());?>.jpg height=150 width=100 border=1px </img

This is what i have tried but gives me a filename of "1234jpg" see the "." is missing? and is still lower case.

<img src=../images/mbr_images/<?php echo H($mbr->getBarcodeNmbr());
      
      $image = jpg;
      $image2 = JPG;
      
      if ($image = $image) {
      echo $image;
      } else {
      echo $image2;
      };?> height=150 width=100 border=1px </img>

can anyone offer any help please?

TIA
Peter

Hello folks, I am new to the forum.

I am having a problem on SBS 2011 creating a ZipArchive with PHP.

Although I have specified the filename to create as "myzip.zip" the file created in the temp folder is "myzip.zip.a10860". If I try again immediately the file becomes "myzip.zip.b10860" and then "myzip.zip.c10860". Of course the numbers will change if I wait a few minutes.

I have also tried creating the file first with fopen() then closing it and trying the ZipArchive::OVERWRITE. Still the same result

I have tried many standard scripts from the net as well as my own very basic script and always the same result.

PHP is set up through Fastcgi.

Any thoughts would be appreciated.

Michael

Hi all,

I am working on the PHP to fetch the data from the database. I would like to fetch the filename only following by:

email1.png
email2.png
email3.png
my_inbox.png

 

When I try this:           

$mailbox_sql = 'SELECT * FROM ' . $mailfolder . ' WHERE email_id = ? AND message_id = ?';
$mailbox = $link->prepare($mailbox_sql);
$mailbox->execute([$id,$message_id]); 

// set the resulting array to associative
$row = $mailbox->fetch(PDO::FETCH_ASSOC);

if (is_array($row)) {
   $attached = $row['attached_files'];
   $attached_files_name = explode('attid: ', $attached);
}

 

 

I am getting this:

0 filename: email1.png
1 filename: email2.png
2 filename: email3.png
3 filename: my_inbox.png

 

 

Here is what I have stored in the database:

 attid: 0 filename: email1.png
 attid: 1 filename: email2.png
 attid: 2 filename: email3.png
 attid: 3 filename: my_inbox.png

 

 

Here is what I want to achieve:

email1.png
email2.png
email3.png
my_inbox.png

 

 

Can you please show me example how I could get the filename when I am fetching the data from the database?

Thanks in advance.
