Reload page with different content?

skinny_monkey

How can i have 2 functions in the same php file, so that one of the functions is triggered when a variable is set?

For instance, one function when the page first loads, to populate a page, and a second function that refreshes the page, but writes different content to it?

I have a page where, as the user logs in, a page of tables is displayed to them containing their user information. When they click on a simple search form, i'd like it to use the same page, but display the search results instead of the user information.

Is this possible?

Just set a variable in the form and then check for it.

<?php
if ($_POST['blah']) {
   echo "This is page two!";
   exit;
}

echo "Welcome to page one...<br><br>";
echo "<form action=".$_SERVER['PHP_SELF']." method=post>";
echo "<input type=hidden name=blah value=1>";
echo "<input type=submit name=submit></form>";

Actually, even that might be overdone, but you get the idea, I hope.

Something that may make it easier for you is to use the switch command.

switch($_POST['submit'])
{
     case "page3";
         //page3
     break;

 case "page2";
      //page 2
 break;

 default:
      //index page
 break;
}

Cheers.

thanks, thats works, and has got me a step closer, but not yet complete.

I have a select box for the search function, with different statuses of progress of reports( compelte, in progress, no action, awaiting information). The user can select these, then enter a search term, and the page should reload with the search results.

The method you gave me above works fine, but if the user doesn't enter anything, i'd like it to retreive all records of that status ie if the textbox is left blank, and "complete" is chosen on the select box, pressing submit will find all records with a status of complete. If the user enters, say, "marketing", and the "in progress" selection is chosen, it will find all records matching the word marketing and with a status of in progress.

the second example works fine, but not the first. How can i implement this with the solution mentioned above?

is there no way to simply call the function from the form ie:
<form name = "searchform" method = "post" action = search()>
?

Thanks for your time

Post your form please.

echo "<form action = ". $_SERVER['PHP_SELF'] ." method = post name = searchform>";
echo "<table cellspacing = 0 border = 0>";
echo "<tr><td colspan = 2>";
echo "<input type = text value ='Look for...' name = SearchTerm size =24>";
echo "</td></tr>";

echo "<tr><td colspan = 2>";
echo '<select name= SearchType>
<option value = "Keyword">Search by Keyword</option>
<option value = "ID">Search by ID</option>
<option></option>
<option value = "Complete">Complete</option>
<option value= "Awaiting Test">Awaiting Test</option>
<option value = "In Progress">In Progress</option>
<option value = "Awaiting Information">Awaiting Information</option>
<option value = "Not Started">Not Started</option>
</select>';
echo "</td></tr></table>";
echo "</form>";

Then the code to process and retreive from the form data is:
//search depending on <select> option
if ($SearchType == "ID")
{
$result = mysql_query("select * from accounts where reportID = '$trimmed' ") or die ("Couldn't Connect");
}

elseif ($SearchType == "Keyword")
{
$result = mysql_query("select * from accounts where description like \"%$trimmed%\" ") or die ("Couldn't Connect");
}

else
{
$result = mysql_query ("select * from accounts where status ='$SearchType' AND description like \"%$trimmed%\" ") or die ("error selecting type");
}

John_Canyon

well.. in this case you would use.

switch($SearchType)
{
	case "Keyword";
	break;

case "ID";
break;

case "Complete";
break;

case "Awaiting Test";
break;

case "In Progress";
break;

case "Awaiting Information";
break;

case "Not Started";
break;

default:
	//default page (form).
break;
}

build it simply using functions (this is how i handle all this stuff)

if ($_POST['someVar']){
    do_process();
}else{
    show_form();
}

function show_form()
{
//html and php to create form here
echo "<form action = ". $_SERVER['PHP_SELF'] ." method = post name = searchform>"; 
echo "<table cellspacing = 0 border = 0>"; 
echo "<tr><td colspan = 2>"; 
echo "<input type = text value ='Look for...' name = SearchTerm size =24>"; 
echo "</td></tr>"; 

echo "<tr><td colspan = 2>"; 
echo '<select name= SearchType> 
<option value = "Keyword">Search by Keyword</option> 
<option value = "ID">Search by ID</option> 
<option></option> 
<option value = "Complete">Complete</option> 
<option value= "Awaiting Test">Awaiting Test</option> 
<option value = "In Progress">In Progress</option> 
<option value = "Awaiting Information">Awaiting Information</option> 
<option value = "Not Started">Not Started</option> 
</select>'; 
echo "</td></tr></table>"; 
echo "</form>"; 

}//end function

function do_process()
{
$var=$_POST['comeVar'];
//check $var for completeness

//run search code
//search depending on <select> option 
if ($SearchType == "ID") 
{ 
$result = mysql_query("select * from accounts where reportID = '$trimmed' ") or die ("Couldn't Connect"); 
} 

elseif ($SearchType == "Keyword") 
{ 
$result = mysql_query("select * from accounts where description like \"%$trimmed%\" ") or die ("Couldn't Connect"); 
} 

else 
{ 
$result = mysql_query ("select * from accounts where status ='$SearchType' AND description like \"%$trimmed%\" ") or die ("error selecting type"); 
}

//show results
}//end function

this way the functions are only ever run when called...and they only get called if the user does something like
1. click the submit button if ($POST['submit'])
2. a var is filled in if ($POST['text_element_name'])
3. a link is clicked if ($_GET['someVar'])

Your method of using functions is exactly what i'm after. I gave my submit button a name, then run a check to see if it had been set:

echo '<input type = "submit" name = "searchbtn">

then:

if ($_POST['searchbtn'])
{
Search();
}else{
other functions
}

I was wondering if you could explain to me how to use the same method but with a hyper link - i've tried:

then

if ($_POST['details])
{
details();
}

but it doesn't seem to be working. I was wondering if its possible to give hyperlinks a name or something?

Thanks

bastien

simple (remeber that for elements contained in the URL, use the $_GET method)

then

//note that in the above link, name is the variable that has a value of details...

if ($_GET['name']optional =="details")
{
details();

}elseif ($_GET['name']optional =="something else") {
//do something else here
}//end if
