[SOLVED] show if form varible not empty

[emediastudios]

I need an alteration to my code to show region only if the form varible from the previous file is not empty.

 

I have a list of properties in a table called employees, database name gcproperty.

Some properties dont have full records in the fields (photo1, photo2, etc..........to photo9. and are empty.

On the show all details page some images are blank as there is no record in the database or where drawn from the form varibles browse page that where also empty.

 

Does this make sense? ???  ???

 

here is the code for image 2, the rest are the same

 

table width="150" border="0">
  <tr>
    <td><a href="images/<?php echo $_POST['photo2']; ?>" target="_blank"><img src="images/<?php echo $_POST['photo2']; ?>" alt="image" width="150" border="0" /></a><br /></td>
  </tr>
</table>

Are you getting paid for being a php programmer?

[jd2007]

do you mean that if $_POST['photo2'] is not empty, then display or not don't display. ...? if that's what you mean...just do this:

 

table width="150" border="0">
  <tr>
    <td>
     <?php
     if (isset($_POST['photo2']))
     {
       echo "<a href='images/".$_POST['photo2']."' target='_blank'><img src='images/".$_POST['photo2']."'      alt='image' width='150' border='0' /></a>";
     }
     else
     {
       echo "N/A";
     }
     ?>
    <br />
   </td>
  </tr>
</table>

 

in the above i use the isset() function to test if $_POST['photo2'] is set or not...if its set, then display the image, else display n/a. see the manual to learn more about variables : http://www.php.net/manual/en/ref.var.php

i used your code and i think im getting a step closer.

Your definately on the right track>

 

When i open the show all details page by itself i get the N/A

But if i open it from the file i post the data from it doesnt work. ???

 

Thyanks for your help champ.

I am a beginner in php, could you explain in a little more detail please, sorry. But i would be so stoked to sort this out.

Thanks again

But if i open it from the file i post the data from it doesnt work.

Sure Here it is

 

</table>
  <table width="645" align="center">
    <tr>
      <td colspan="2" align="left" valign="top" bordercolor="#000000" bgcolor="#F1F1F1"><div align="left"><span class="style1"><u> <?php echo $_POST['name']; ?></u></span> </div>
      <div align="right"></div></td>
    </tr>
    <tr>
      <td width="173" align="left" valign="top" bordercolor="#000000" bgcolor="#FFFFFF"><table width="156" border="0">
          <tr>
            <td width="150" height="403" valign="top">
           <table width="150" border="0">
  <tr>
    <td> <br /></td><?php
     if (isset($_POST['photo2']))
     {
       echo "<a href='images/".$_POST['photo2']."' target='_blank'><img src='images/".$_POST['photo2']."'      alt='image' width='150' border='0' /></a>";
     }
     else
     {
       echo  "N/A";
     }
     ?>
  </tr>
</table>

              <br />
          <table width="150" border="0">
  <tr>
   <td><a href="images/<?php echo $_POST['photo3']; ?>" target="_blank"><img src="images/<?php echo $_POST['photo3']; ?>" alt="image" width="150" border="0" /></a><br /></td>
  </tr>
</table>

            <br />
           <table width="150" border="0">
  <tr>
    <td><a href="images/<?php echo $_POST['photo4']; ?>" target="_blank"><img src="images/<?php echo $_POST['photo4']; ?>" alt="image" width="150" border="0" /></a><br /></td>
  </tr>
</table>
<br />

            <table width="150" border="0">
  <tr>
    <td><a href="images/<?php echo $_POST['photo5']; ?>" target="_blank"><img src="images/<?php echo $_POST['photo5']; ?>" alt="image" width="150" border="0" /></a><br /></td>
  </tr>
</table>

            <br />
            <table width="150" border="0">
  <tr>
    <td><a href="images/<?php echo $_POST['photo6']; ?>" target="_blank"><img src="images/<?php echo $_POST['photo6']; ?>" alt="image" width="150" border="0" /></a><br /></td>
  </tr>
</table>

            <br />
            <table width="150" border="0">
  <tr>
    <td><a href="images/<?php echo $_POST['photo7']; ?>" target="_blank"><img src="images/<?php echo $_POST['photo7']; ?>" alt="image" width="150" border="0" /></a><br /></td>
  </tr>
</table>

 

And this is the file code that sends the data

 

<form action="full_details.php" method="post" enctype="multipart/form-data" name="properties" target="_self" id="properties">
      <table width="600" align="center" bgcolor="#F1F1F1">
      <tr>
        <td width="437" align="left" valign="top" bordercolor="#000000" bgcolor="#FFFFFF"><span class="style1"><u><?php echo $row_Recordset1['name']; ?></u></span><span class="style3">
        <label>
        <input name="name" type="hidden" id="name" value="<?php echo $row_Recordset1['name']; ?>" />
        </label>
        <label></label>
        </span> <span class="style3"><br />
          <span class="style5"><?php echo $row_Recordset1['price']; ?>
          <label></label>
          <label>
          <input name="price" type="hidden" id="price" value="<?php echo $row_Recordset1['price']; ?>" />
          </label>

          </label>

      </tr>

    </table>
    </form>

I used this code and it works like i wish, seems strange as to me it feel like its reversed.

 

<?php
     if (!empty($_POST['photo2']))
     {
       echo "<a href='images/".$_POST['photo2']."' target='_blank'><img src='images/".$_POST['photo2']."'      alt='image' width='150' border='0' /></a>";
     }
     else
     {
       echo  "";
     }
     ?>
