[SOLVED] Help with keeping form fields populated using sessions

[CodeMama]

I found a couple examples and have tried and they all seem to be based around this but it doesn't work anyone see my error?

 

  <tr>
                                <td width="20%" align="right" height="30"><div class="admin_Caption">Name:</div></td>
                                <td width="80%" height="30"><input name="searchname" type="text" size="30"
                                <?php
                                if(isset($_SESSION['searchname']))
                                {
                                  echo " value='" . $_SESSION['searchname'] . " ['searchname'] '";
                                }
                                  ?>
                                  >
                                </td>
                                
                                                                
                              </tr>

 

The session_start() is at the top of my page along with checking for the sessions.... help help

That code looks ok. What is it doing now? Is the form field populated?

 

If its not can you post how the $_SESSION['searchname'] variable is being defined?

[smerny]

You're wanting it to... like for example if searchname is "CodeMama"

 

you want it to say this?  value='CodeMama ['searchname'] '

 

because thats what you have set... and actually that will create a problem because you have single quotes within single quotes.

 

I would assume you just want value='CodeMama'... which means you just do this:

 

echo " value='" . $_SESSION['searchname'] ."'";

Thanks going to change it to smerny suggestion see if on submit it holds the values ...I may be back

 

[CodeMama]

well I added it and now when I reload the page it wouldn't release the sessions, so I put this

    // Check if there was an empty search sent
							    if(isset($_SESSION['noVarsSent']))
							    {
							      echo "<p><b>No values were submitted for the search.</b></p>";
							      // Unset it so a reload of page doesn't redisplay the error
							      unset($_SESSION['noVarsSent']);
							      unset($_SESSION['results']);
							      unset($_SESSION['searchname']);
							      unset($_SESSION['address']);
							      unset($_SESSION['bmonth']); 
							      unset($_SESSION['bday']); 
							      unset($_SESSION['byear']); 
							      unset($_SESSION['emonth']); 
							      unset($_SESSION['eday']);
							      unset($_SESSION['eyear']); 

							      unset($_SESSION['totalNumberOfRestaurants']);
							   
							     
							    }else{
							    $_SESSION['searchname'] = $_POST;
							    $_SESSION['address'] = $_POST;
							    $_SESSION['bmonth'] = $_POST;
							    $_SESSION['bday'] = $_POST;
							    $_SESSION['byear'] = $_POST;
							    $_SESSION['emonth'] = $_POST;
							    $_SESSION['eday'] = $_POST;
							    $_SESSION['eyear'] = $_POST;

							    }
							    


							  ?>

 

now when I reload the page it says "Array" in the search text boxes?

[smerny]

$_SESSION['searchname'] = $_POST;

 

unless it's something about php that i don't know about, that wont do anything...try

 

$_SESSION['searchname'] = $_POST['searchname'];

 

========

 

also not sure how this is getting set?

 

if(isset($_SESSION['noVarsSent']))

 

I'm also unsure of what the bigger picture looks like in this situation so maybe thats why I'm confused

[CodeMama]

wow this is getting tricky...I put the $_POST =['blah'] in there and it just gave me a bunch of undefined variable errors, so I put it like this

which got rid of the errors but...doesn't keep the values

  <tr>
						    <td width="20%" align="right" height="30"><div class="admin_Caption">Name:</div></td>
						    <td width="80%" height="30"><input name="searchname" type="text" size="30"
						    <?php
						    if(isset($_SESSION['searchname']))
						    {
						      echo " value='" .   $_SESSION['searchname'] = $_POST['searchname'] ."'";
						    }
						      ?>
						      >
						    </td>
						    
						    							    
						  </tr>

[smerny]

your code is saying...

 

if

$_SESSION['searchname']

is already set, set it... otherwise leave it unset ?

 

 

does your form action load this page that you are taking the code from? if so you could just switch

 

if(isset($_SESSION['searchname']))

with

if(isset($_POST['searchname']))

[darkfreaks]

Try this:

 

<?php
if(isset($_POST['blah'])){

$_SESSION['blah']= $_POST['blah'];

echo $_SESSION['blah'];

}

?>
