php making image links using loops

Hi Guys,

Trying to make a little script that will write all my a href links as I've renamed all my files using Adobe bridge to 001, 002 etc... I wrote this but I can't get it to work, I only really went through PHP basic course yesterday so I'd appreciate an explanation too, I feel that I'm close though?

" <?php

for($imagenumber = 001; $imagenumber < 100; $imagenumber++){

echo "< website reference* . <?php echo $imagenumber ?> . "width="100%"> <(closing off a tag)>"

}

?> "

  • = treehouse removes html ref links I think as it doesn't appear

Thank you!

for($imagenumber = 001; $imagenumber < 100; $imagenumber++){ echo "<a href="http://www.imagelink.com/images/category/" . <?php echo $imagenumber?> . "width="100%"> </a>" }

Hi Juice Dont think assigning 001 as an integer like that will work. I ran your code and the output was 1,2,3 not 001,002 etc because php is converting 001 to an integer 1 so you end up with 1,2,3. I think if you append a string in front of the number like this.

<?php 
$imagenumber_s="00";
 for($imagenumber = 001; $imagenumber < 100; $imagenumber++)
    { 
        $imagenumber=$imagenumber_s.$imagenumber;
        echo 'website reference* '.$imagenumber." width='100%' "."</br>"; 

    } 
?>

Ok I understand that bit, how would I write it so the code generated would be www.imagelink.com/image/category/001 - 002 003 etc?

<?php 

      for($imagenumber = 1; $imagenumber < 100; $imagenumber++){

echo "<p> <website link" . $imagenumber . " width="100%"> <a tag> </p>" ; }?>

is as far as I've got - Thanks for your help! Sorry I'm having troubles displaying all of my code on there for some reason

the code in theory works great so thank you for your help i was really close in it being correct! however once it reaches 9 afterwards it will produce 0010, 0011, 0012 am I correct in what I'm thinking? As its a constant value of $imagenumber_s? not, would have to be and if statement? so when image number == 009, 

$imagenumber_s="00";
 for($imagenumber = 001; $imagenumber < 100; $imagenumber++)
    { 
        $imagenumber=$imagenumber_s.$imagenumber;
        echo 'website reference* '.$imagenumber." width='100%' "."</br>"; 

    } if else{

 $imagenumber_b = 0;
($imagenumber = 9; $imagenumber < 99; $imagenumber++){

$imagenumer = $imagenumber_b.$imagenumber'
echo 'website reference* '.$imagenumber." width='100%' "."</br>";

}

then continue so its 010, 011, 012?

how many images do you have and how exactly you want it output ?? might be to write the code once and not have to do two if statements?? and yes after 9 it will output 0010,0011,0012 ect

its like 280 images all together but like 50 in each folder. I'm just looking for it to produce the html text so I can copy it into this input editor as it will save so much time, sorry about the messy replies, treehouse is blocking them.

try this just change the variables that should work. or just change the code around to get the desired html result.

<?php
$yourfoldername="foldername";
$no_of_images=50;
$counter=0;
$imagenumber_s="www.imagelink.com/image/category/".$yourfoldername."/";

 for($i = 1; $i <= $no_of_images; $i++)
    { 
        $counter++; // using this counter to check the last round of the loop to add            the - only when it is not the last counter
           if($counter ==$no_of_images){
                         $imagenumber_s=$imagenumber_s.'00'.$i;
               }
             else{
                   $imagenumber_s=$imagenumber_s.'00'.$i.'-';
              }

     } 
echo $imagenumber_s." width=100%";
   ?>

Hi Guys, Managed to do it after using yours as reference I simplified it a bit. note that the images are the same name as the folder.

 <?php
$yourfoldername="foldername";
$no_of_images=50;
$counter=0;
$format = ".jpg'";

$imagenumber_s="<img src='http://www.website.com/wp-content/uploads/category/".$yourfoldername."/".$yourfoldername."_";

 for($i = 1; $i <= $no_of_images; $i++)

 {

   echo $imagenumber_s."00".$i.$format .  " width='100%'>this is a link</a>"    ;

     } 
   ?>
