PHP - Trying To Echo Out String Variables In A Form
I need to echo out some string variables in a form. I also want to add some validation for Name, email etc. I think I have the code right or close, but I can an error on the index.php page which is.
"Fatal error: Call to undefined function form_row_class() in index.php on line 14" here is the code for the form <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>String Tester</title> <link rel="stylesheet" type="text/css" href="main.css"/> </head> <body> <div id="content"> <h1>String Tester</h1> <form action="submit.php" method="post"> <table> <tr class="<?php echo form_row_class("name") ?>" > <th><label for="first_name">Name</label></th> <td> <input name="first_name" id="first_name" type="text" value="<?php echo h($_POST['name']); ?>" /> <?php echo error_for('name') ?> </td> </tr> <tr class="<?php echo form_row_class("email") ?>"> <th><label for="email">Email Address</label></th> <td> <input name="email" id="email" type="text" value="<?php echo h($_POST['email']); ?>" /> <?php echo error_for('email') ?> </td> </tr> <tr> <th></th> <td><input type="submit" value="submit" /></td> </tr> </table> </form> <h2>Message:</h2> <?php echo "<table>"; echo "<tr><td>"; echo $name; echo "</td></tr>"; echo "<tr><td>"; echo $email; echo "</td></tr>"; echo "<tr><td>"; echo $phone; echo "</td></tr>"; echo "</table>"; ?> </div> </body> </html> and the submit portion <?php // If request is a form submission if($_SERVER['REQUEST_METHOD'] == 'POST'){ // Validation // Check first_name is non-blank if(0 === preg_match("/\S+/", $_POST['name'])){ $errors['name'] = "Please enter a name."; } // Check email is valid (enough) if(0 === preg_match("/.+@.+\..+/", $_POST['email'])){ $errors['email'] = "Please enter a valid email address."; } // validate a phone number if( !preg_match("/^([1]-)?[0-9]{3}-[0-9]{3}-[0-9]{4}$/i", $phone) ) { echo 'Please enter a valid phone number'; } // If no validation errors if(0 === count($errors)){ // Sanitize first, last, and email $name = mysql_real_escape_string($_POST['name']); $email= mysql_real_escape_string($_POST['email']); $email= mysql_real_escape_string($_POST['phone']); } // Helpers function form_row_class($name){ global $errors; return $errors[$name] ?

Similar TutorialsWhat I would like to find out is how I can echo out all the variables that are in use in the visitors visit. And have these echoed on the page. (for error checking purposes) some of my variables i.e. $username or $email and a few others are being cleared of its content and I can not find any problems searching all the files for the variable name and checking the lines but think that some other variable is in turn causing theproblems. so wanting to find a way to place an echo line that shows all the variables and then have the next line exit; and just move these two new lines around my scripts to find out where the problems might be. Hello all, I'm passing variables through a URL. This will work: echo $v4; But neither of these will: echo "<a href='test.php?v4=$v4'>Places</a>"; echo "<a href='test.php?v4=".$v4."> Places</a>"; It WILL work if I hardcode v4, like so: echo "<a href='test.php?v4=Utah'>Places</a>"; But that's useless to me, as I don't want to have to write 50 If statements for every database entry. Does anyone know how to fix this? Thanks! Hello, I just wanna know if any such commands are available in php for making a variable as such like - $variable = " blah blah .. . . . index.php?X=<?php echo $_GET['x']; ?>..........blah"; thank you Hi, I want to send the following variable using the $_GET function: Hi all, how would I write a string like this in an echo statement so the javascript runs? <a href="javascript:ajaxpage('test.php', 'content');">test</a> how do i get the image to show as the code i have is echoing what i have been told is binary, not confirmed. and not the images. all images are .jpg Code: [Select] $allowed_types = array('png','jpg','jpeg','gif'); $imgdir = '/home/mysite/ftpfolder'; $imgFilesArray = scandir($imgdir); foreach ($imgFilesArray as $imgkey => $imgvalue) { $imgInfo = pathinfo($imgdir . '/' . $imgvalue); $imgExtension = $imgInfo['extension']; if(in_array($imgExtension, $allowed_types)) { readfile($imgdir . '/' . $imgvalue); //echo '<img src = "'. $imgdir .'/'. $imgInfo['basename'].'" alt="" />'; } } images are FTP'd to the ftpfolder and can not be placed anywhere else but this folder due to security reasons. Could someone help me crack this issue. I am trying to insert a variable into an flash object echo string's src. I've try many variations but can't figure it out.

It always displays the message even if the information is present in the url and the $_GET should work. Here's the code I've got:
<h3>
<?php
$qset = strpos($_SERVER['SCRIPT_NAME'], 'qtitle');
if ($qset === false) {
echo "You haven't added any questions yet.";
} else {
echo $_GET['qtitle'];
}
?>
</h3>
The URL will contain "qtitle=(something)" if they've filled out a form on the prior page.
Can someone tell me what I'm doing wrong? I have a feeling I've overcomplicated things...
Thanks again!
The below might be a noob question but, I concatenate two spaces in the below string $new_hebrew_date_string = $hebrewMonthName . ' ' . $hebrewDay . "%"; yet when I execute echo "<br />new_hebrew_date_string is $new_hebrew_date_string<br />"; printf("hebrew_date_string is: %s <br />", $new_hebrew_date_string); Only one space is output in between $hebrewMonthName and $hebrewDay regardless of how many spaces I pad the string with. Strangely enough, the string $new_hebrew_date_string is correctly padded w/spaces when I pass it as a parameter to a mySQL stored procedure. Any ideas anyone? Thank you. $id[] = 12345; $id[] = 12345; $id[] = 12345; $id[] = 12345; $id[] = 12345; how would I combine these into a string "12345,12345,12345,12345,12345" hello, im wondering how to properly code the following.

How do i go about placing the values into variables so for example: $success = "true"; $delivered = "true"; $message = "Signed for by: D ANDERSON"; etc.... My mind has gone blank and im having one of those days, any help would be greatly appreciated. Thanks I have a string that looks like /index.php?g1=111&g2=222&g3=333. How can I obtain the value of g1 (i.e. 111)? It does not represent the current state of the server thus I cannot just use $_GET. It also is not necessarily the first item. The script below appears to work, however, http://php.net/manua...n.parse-url.php states This function is intended specifically for the purpose of parsing URLs and not URIs. However, to comply with PHP's backwards compatibility requirements it makes an exception for the file:// scheme where triple slashes (file:///...) are allowed. For any other scheme this is invalid. It appears that my string is a URI and not a URL, but I might be wrong. How should this be accomplished
<?php
$str='/index.php?g1=111&g2=222&g3=333';
$array=parse_url($str);
parse_str($array['query'],$get);
echo("<p>{$get['g1']}</p>");
?>
Hi Guys and Girls, Long time lurker, first time poster! I am usually able to read through the forums and find and answer without having to start a new thread but I've tried my best to no avail. I am having trouble with the following code: $afname="Gareth"; $alname="B"; $awayoption.="<OPTION VALUE=\"".$afname." \"".$alname."\">".$afname." ".$alname; I would want that to produce the following: Code: [Select] <OPTION VALUE=Gareth B">Gareth B The actual result at the moment is: Code: [Select] <OPTION VALUE="Gareth "B">Gareth B It has an extra " in the middle. Any ides or help would be great! Cheers Pretty simple I would think but I'm unsure on the syntax. I have a variable, $ename. It's actually data from a form that I pass to said variable. What I want is to then in turn use this string in a mkdir() function. Something like Code: [Select] mkdir("dir/folder/$ename/"); Obviously that doesn't work. I'd imagine I have to use some sort of . syntax. Code: [Select] $query = "SELECT content FROM license WHERE serial = '".$serial."'"; I have an audit trail that record users ids and a copy of the sql string for any updates they make to my application. This is very easy for me to follow to find exactly where changes happened but do end users it is a bit of a challenge. Has anyone seen or made a script that can either compare two sql strings to see what fields have different values or a script that takes an SQL string and outputs its field names and values to an array that I can use for comparisons? Example being the look at a update made by user X, the database pulls the sql for that change then looks for the previous change up any user before (update sql should have a value for all fields) then compares to see what user X changed. If not im thinking of case statement to divide sql request between inserts and update then writing a script to split the strings based on where the commas were. Any thoughts?
