I did not quite know how to label this post hence the unusual title.
I am trying to modify some code that I have written to save the choosen line that is output from an SQL query, using SESSION to make it available in a later script.
To achieve this I have started a form with a radio button inside the while loop that outputs the query items that meet the criteria set by a form in the previous script.
Before I modified this script it worked albeit without the choice coding.
When I submit the choices on the previous script the query is run and it ouputs the results as a table, with an extra column which contains a radio button. I have for test purposes output the value of the variable to check that the variable is storing the value correctly. When I choose a line that the query has output and clcked on the submit button it seems to be causing the code to think it has not got an Event set and displays the error message "You have selected an invalid Event.
Please try again.", on line 21 which is part of the code I wrote to make sure that an Event has been choosen, instead of proceeding on to the next script.
Here is the complete script:
<?php
session_start();
include("cverse_connect.php");
doDB();
//check for required info from the query string
//verify the Event exists
$verify_Event_sql = "SELECT ID, Event_Type FROM Events WHERE ID = '".$_POST["Event_Type"]."'";
$verify_Event_res = mysqli_query($mysqli, $verify_Event_sql) or die(mysqli_error($mysqli));
echo $_POST["Event_Type"];
echo $_POST["Mood"];
if (mysqli_num_rows($verify_Event_res) < 1) {
//this Event does not exist
$display_block = "<p><em>You have selected an invalid Event.<br/>
Please try again.</em></p>";
} else {
//get the Event ID
while ($Event_info = mysqli_fetch_array($verify_Event_res)) {
$Event_ID = stripslashes($Event_info['ID']);
$Event_Name = ($Event_info['Event_Type']);
}
$verify_Mood_sql = "SELECT ID, Event_Sub_Type FROM Event_Sub WHERE ID = '".$_POST["Mood"]."'";
$verify_Mood_res = mysqli_query($mysqli, $verify_Mood_sql) or die(mysqli_error($mysqli));
if (mysqli_num_rows($verify_Mood_res) < 1) {
//this Event does not exist
$display_block = "<p><em>You have selected an invalid Mood.<br/>
Please try again.</em></p>";
}
while($Mood_info = mysqli_fetch_array($verify_Mood_res)) {
$Mood_ID = ($Mood_info['ID']);
$Mood_Name = ($Mood_info['Event_Sub_Type']);
}
//gather the Events
$get_Event_sql = "SELECT Verses.ID AS versesID, Verses.Verse, Verses.Sub_Type, Verses.Event, Events.ID AS eventsID, Events.Event_Type, Event_Sub.ID AS event_SubID, Event_Sub.Event_Sub_Type
FROM Verses
LEFT JOIN Events
ON Verses.Event = Events.ID
LEFT JOIN Event_Sub
ON Verses.Sub_Type = Event_Sub.ID
WHERE Verses.Event = '".$_POST["Event_Type"]."' And Verses.Sub_Type = '".$_POST["Mood"]."'
ORDER BY Verses.ID ASC";
$get_Event_res = mysqli_query($mysqli, $get_Event_sql) or die(mysqli_error($mysqli));
//create the display string
$display_block .= "
<table width=\"70%\" cellpadding=\"3\" cellspacing=\"1\" border=\"1\" BGCOLOR=\"#87CEEB\" >
<tr>
<th>ID</th>
<th>VERSE</th>
<th>MOOD/SUB TYPE</th>
</tr>";
while ($Verse_info = mysqli_fetch_array($get_Event_res)) {
$Verse_id = $Verse_info['versesID'];
$Verse_text = nl2br(stripslashes($Verse_info['Verse']));
$Mood_info = $Verse_info['Event_Sub_Type'];
$VID = $Verse_id;
//add to display
$display_block .= "
<tr>
<td width=\"1%\" valign=\"top\">".$Verse_id."<br/></td>
<td width=\"55%\" valign=\"top\">".$Verse_text."<br/></td>
<td width=\"35%\" valign=\"top\">" .$Mood_info."<br/></td>
<td width=\"35%\" valign=\"top\">
<form .method=.\"POST\" .action=\"VInput1.php\">
<input type=\"Radio\" value=\"$VID\">
$VID
</td></tr>";
}
$display_block.="<input type=submit value=Choose Verse>";
//free results
mysqli_free_result($get_Event_res);
mysqli_free_result($verify_Event_res);
//close connection to MySQL
mysqli_close($mysqli);
//close up the table
$display_block .= "</table>";
}
$_session['Test']=$_POST[$VID]
