PHP - How To Make Link That Selects Certain Stuff

I basically have a PHP Search Form, and when a user fills in a form it outputs the results. Each result displays a image of a property, how could i make them images have their own unique link which will take them directly to the page of the property being shown?

Im using PHP and mySQL tables

Any help is appreciated,

Thank You.

Heres the PHP that outputs the results:
Code: [Select]

<?php
require_once 'mstr_ref.php';
function san($input){
if(get_magic_quotes_gpc()){
$input=stripcslashes($input);
}
$output = mysql_real_escape_string($input);
return $output;
}
if(isset($_POST['submit'])){
$pVars = array('area'=>$_POST['areas'], 'propType'=>$_POST['prop_type'], 'saleType'=>$_POST['ptype'], 'minB'=>$_POST['min_bedrooms'], 'maxB'=>$_POST['max_bedrooms'], 'minP'=>$_POST['min_price'], 'maxP'=>$_POST['max_price']);
foreach ($pVars as $k=>$v){
$v = san($v);
}
$sql = new makeQuery();
$sql->manAdd('location_id', $pVars['area']);
if($pVars['propType'] != 'Any'){
$sql->manAdd('catagory_id', $pVars['propType']);
}
if ($pVars['maxB'] > 0){
$sql->manAdd('bedrooms', $pVars['maxB'], '<=');
}
if($pVars['minB'] > 0){
$sql->manAdd('bedrooms',$pVars['minB'],'>=');
}
if($pVars['saleType'] != 'Any'){
if($pVars['saleType'] == "forsale"){
$sql->manAdd('market_type', 'sale');
if($pVars['minP'] != 0){
$pVars['minP'] = $pVars['minP'] * 1000;
}
if($pVars['maxP'] != 0){
$pVars['maxP'] = $pVars['maxP'] * 1000;
}
}
if($pVars['saleType'] == 'forrent'){
$sql->manAdd('market_type', 'rent');
}
}

$qry = $sql->sqlStart.$sql->stmt.'Group By property.id';
$results = mysql_query($qry) or die (mysql_error()."<br />|-|-|-|-|-|-|-|-|-|-|-|-<br />$qry");
if(mysql_num_rows($results) < 1){
die ("Sorry, No Results Match Your Search.");
}
while($row = mysql_fetch_assoc($results)){
echo '<div class="container" style="float:left;">';
echo '<div class="imageholder" style="float:left;">';
echo "<img class='image1' src='{$row['image_path']}' alt='{$row['summary']}'> <br />";
echo '</div>';
echo '<div class="textholder" style="font-family:helvetica; font-size:14px; float:left; padding-top:10px;">';
echo "{$row['summary']}";
echo "<span style=\"color:#63be21;\"><br><br><b>{$row['bedrooms']} bedroom(s) {$row['bathrooms']} bathroom(s) {$row['receptions']} reception room(s)</b></span>";
if($row['parking'] != null){
echo "<span style=\"color:#63be21;\"><b> {$row['parking']} parking space(s)</b></span>";
}

echo '</div>';
echo '<div style="clear:both"></div>';
}

}
else{
echo "There was a problem, please click<a href='index.php'> Here </a>to return to the main page and try again";
}
?>

Lets say that I want to make a certain word (or words) on a page a link. How would I make it a link without having to code in a link.

Some site have adds on certain words; one day and not the next day. I am looking for similar feature, but less intrusive. No pop-up, just a link.

I have a site, and there is an image with a link to another page, how can I make it so this is the only way to get to that page is by clicking on that image, and not by typing www.mywebsite.com/page.php into the address bar in a browser?

I have a table where it displays some data. How do I make this Code: [Select]
echo "<td>" . $row['title'] . "</td>"; into a link?

Seems to be a basic question, but I couldn't find an answer nor figure it out on my own.

Basically I have a script that takes out specific data out of the database, the script works on its own, now I just need a way to make the user execute it with a link or a button.

Example:
Category: [Smileys] - [Category2] - [Category3] - etc.

As soon as the user clicks on [Smileys] all data in the database which contains the word smileys in the category field gets selected and outputted as a list.

Again the script works, I just need to be able to execute it with a button.

If I understood it correctly I have to run the script by adding a
if (isset($_POST['Smileys'])) {
in front of the script.

But how do I build the connection with the text link?

I would like to know how to make my links show that it's active. For example if I click on a link that says overview then that link has to be highlighted.

This is the code that I have:

Code: [Select]
<?php 
if (isset($this->_params['submenus']) && is_array($this->_params['submenus'])){
foreach ($this->_params['submenus'] as $submenu){
?>
<li class="active"><a href="<?php echo $this->get_uri("/{$submenu['controller']}/{$submenu['action']}") ?>" onclick="javascript:return setSubMenu(<?php echo $submenu['id'] ?>);"><?php echo strtoupper($submenu['name'])?></a></li>
<?php
}
}
?>

Unfortunately with this code all the links are selected as active.

Hi People.

I am doing quite well with my www.airfieldcards.com website which is information for pilots in the UK and ireland should they wish to visit another airfield.

It is in the form of a flight guide for free.

Each card is held in a database and the cards are shown on the site by loading the following script
/php/results.php?id=132

In the above example the card for c-moor in Ireland would be loaded.

I want to be able to add a link within the cards that will give the user "the code" to enter that card within their own website.

Sort of a "click here to get the code to add to your website"

Then opening a separate box in a new window that had something like this in it.

Copy and Paste the following code into your website
Code: [Select]
<iframe width="720" height="1500" frameborder="0" scrolling="no" marginheight="0" marginwidth="0" src="http://airfieldcards.com/php/results.php[b][i]"what goes here?"[/i][/b]
What would I put into the bit "what goes here?" to dynamically load that specific card? and give the user the correct code to add into their own site?

Thanks in advance, you guys on here have always been brilliant.

This is the code I have now however when you click next to view more results it says please enter a search..., (there is more code above this however I thought that the problem would be within the code provided.)

$currPage = (($s/$limit) + 1);

//break before paging
  echo "<br />";

  // next we need to do the links to other results
  if ($s>=1) { // bypass PREV link if s is 0
  $prevs=($s-$limit);
  print "&nbsp;<a href=\"$PHP_SELF?s=$prevs&q=$var\">&lt;&lt;
  Prev 10</a>&nbsp&nbsp;";
  }

// calculate number of pages needing links
  $pages=intval($numrows/$limit);

// $pages now contains int of pages needed unless there is a remainder from division

  if ($numrows%$limit) {
  // has remainder so add one page
  $pages++;
  }

// check to see if last page
  if (!((($s+$limit)/$limit)==$pages) && $pages!=1) {

  // not last page so give NEXT link
  $news=$s+$limit;

  echo "&nbsp;<a href=\"$PHP_SELF?s=$news&q=$var\">Next 10 &gt;&gt;</a>";
  }

$a = $s + ($limit) ;
  if ($a > $numrows) { $a = $numrows ; }
  $b = $s + 1 ;
  echo "<p>Showing results $b to $a of $numrows</p>";
 
?>

Hi Guys,

I am a typical newbie with a twist, i program in VB, recently moved to PHP.

I need help, preferable an example, but first let me explain what i have.

I have a .tpl page that has 3 drop down boxes, one of these is populated from within the .tpl page itself. The other 2 i waant to pupulate from a SELECT on a database from a .php file.

The .TPL file i have so far is:-

Code: [Select]
<style type="text/css">

Now from here i expect the user to select a date from the date box, ( Ideally i would like the other 2 options to only become visible once a selection on the date has been made, i would also like to retain the selected in the date box once the form has been submited.

Now the code i have for the PHP so far is quite long winded as my PHP skills are not so good, although i am learning fast.

Code: [Select]

            'REGION_FILTER' => str_replace("&", " & ", $region_filter_options),

Now my questions are these:-

1) In the .tpl file hows can i submit from any of the dropdown boxes and retain the selection after submission
2) How can i have it so that the second and third drop down boxes are only visible after the previous one, ie the first box ( date ) has to have a selection before the Region ( 2nd one ) is visible and so
3) How can i reduce the amount of code to cover all options in building a select statement or is Switch - case the best way.

I would greatly appreciate help with this and even more so for some example of what i am asking for so i can learn from them.

Okay, I currently have a query that is like:

Code: [Select]
$sql = "SELECT SQL_CALC_FOUND_ROWS a.ItemID, a.spec, a.description, a.sport, a.category, a.price, a.unit_qty, a.is_visible, a.AdminID,
b.name, b.ItemID as catID, c.Name as nameSport, c.ItemID as sportID
FROM purchase_request_category_item as a
LEFT JOIN purchase_request_category as b ON b.itemID = a.category
LEFT JOIN ro_school_sports as c ON c.ItemID = a.sport
WHERE a.AdminID = '".$dist."'
GROUP BY a.ItemID, b.name, c.Name
ORDER BY a.ItemID DESC LIMIT ".
$start.",".$limit;

I am building a custom search function which I intend to be able to change the WHERE line to:

WHERE a.AdminID = '".$dist."' ".$query


$query will be created via if statements for every element in the form which will be called either by the button on the form, or the links in my pagination.

The form would have the following:

Level(s): dynamic field, Multi Select
Status: Both/Enabled/Disabled single select
Sports: dynamic field, Multi Select

Category: dynamic field, single select.

the sport column is a single selected item on the add page, its of type int(11)

the levels table, is also a multi select on the add item page, and is of the type set('1','2','3','4','5','12','13')

So real question is I guess, how on earth do I work with these 2 multi selects to create this search? 

Hi,   I would like to store sql query strings in a database. A query might look this like:   SELECT * from ListTable where id = '$id'   The idea would be to retrieve the string and run it as a SQL string. $id would be defined in the procedure so the idea is that when I send the SQL String through, $id would be replaced with its value and everything would work.   Under normal circumstances, the code would look like this:

$id = "somevalue";
$lcSQL = "SELECT * from ListTable where id = '$id'";

I would pass the SQL select off to mySQL and all is right with the world. I just want to store the string in a database, retreieve it and use it.   Thanks for your help in advance...    

Hi guys, thank for any help. This does not appear like a difficult problem but it has me stymied. I have several selects, the 1st item of each is "--Specify--" so that the user has to specifically choose an item. Once an item is selected on any select the others should be set to the 1st item or "--Specify--" to avoid confusion.

If you want to see the complete code it on this web page: http://chordsandguitar.com/progressions-test.php

The relevant code is:

Code: [Select]
if ($prog1_menu != "--Specify1--")
{
$prog2_menu = "--Specify--";
echo "set prog2 to Specify";
}

if ($prog2_menu != "--Specify2--")
{
$prog1_menu = "--Specify--";
echo "set prog1 to Specify";
}

echo "<form action = \"progressions-test.php?s_sort_all=$sort_all&s_prog1_menu=$prog1_menu&s_prog2_menu=$prog2_menu&s_prog1_trigged=$prog1_trigged&s_prog2_trigged=$prog2_trigged\" method = \"GET\">";
//also stores the values of the drop-downs when Select button is pushed so they can be retrieved when the web page is loaded again



echo "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Ascending bass line";
echo "<br />";
echo "Select a progression: <a href=\"http://www.chordsandguitar.com/progressions-test.php?s_sort_all=All&s_prog1_menu=--Select--&s_prog2_menu=--Select--\"\"><big>ALL</big></a>";
echo "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;";

echo "<select name=\"prog1_menu\"  onchange=\"this.form.submit();\">";

echo "<option value=\"--Specify1--\">--Specify--</option>";
if ($prog1_menu == "ii-iii-IV-V progression") echo "<option SELECTED value=\"ii-iii-IV-V progression\">ii-iii-IV-V progression</option>";
else echo "<option value=\"ii-iii-IV-V progression\">ii-iii-IV-V progression</option>";
if ($prog1_menu == "I-ii-IV-V progression") echo "<option SELECTED value=\"I-ii-IV-V progression\">I-ii-IV-V progression</option>";
else echo "<option value=\"I-ii-IV-V progression\">I-ii-IV-V progression</option>";
if ($prog1_menu == "I-iii-IV-V progression") echo "<option SELECTED value=\"I-iii-IV-V progression\">I-iii-IV-V progression</option>";
else echo "<option value=\"I-iii-IV-V progression\">I-iii-IV-V progression</option>";
echo  "</select>";

echo "&nbsp;&nbsp;&nbsp;";

echo "<select name=\"prog2_menu\" onchange=\"this.form.submit();\">";

echo "<option value=\"--Specify2--\">--Specify--</option>";
if ($prog2_menu == "I-sharpIo7-ii7-sharpIIo7 progression") echo "<option SELECTED value=\"I-sharpIo7-ii7-sharpIIo7 progression\">I-#Io7-ii7-#IIo7 progression</option>";
else echo "<option value=\"I-sharpIo7-ii7-sharpIIo7 progression\">I-#Io7-ii7-#IIo7 progression</option>";
if ($prog2_menu == "I-sharpIo7-ii7-V7 progression") echo "<option SELECTED value=\"I-sharpIo7-ii7-V7 progression\">I-#Io7-ii7-V7 progression</option>";
else echo "<option value=\"I-sharpIo7-ii7-V7 progression\">I-#Io7-ii7-V7 progression</option>";
echo  "</select>";

echo "</form>";
I am trying to identify which select box has been used so that I can set all the other boxes to the 1st item but I wind up re-setting all the boxes.

Cheers,

Jacques

Hey guys there is probably a simple fix to this but i am just not seeing it    ... Im createing a form that has error catching and self submitting valuse. I am trying to use a for loop to create all of the values and if the form is returned with an error then the correct values will still be filled out but i cant seem to get this loop to work. Every time i submit the form it doesnt matter what option i select it always comes back with the last one in the list or 30 in this case.

the problem code is below.. Any help would be appreciated.

Code: [Select]

<?php
for($i=1; $i<=30; $i++){
echo'<option value="'.$i.'"';
if(isset($_POST['petsAge'])== $i){ echo ' selected="selected"';}
echo '>'.$i.'</option>';
}
?>

Hello,   Any ideas why server resources not exhausted on the code below, when my.cnf and php.ini are both set to use half the resources each? PHP & MySQL will both utilize all allotted resources on other scripts, so it's not a tuning problem. There is no script-side tuning.   The bottleneck: pdo select as shown below

foreach($bigList as $listObject) {
                $sql = $dbl->prepare("SELECT * FROM fewMillionRows WHERE indexedCol1=:indexedCol1 AND indexedCol2=:indexedCol2 AND indexedCol3=:indexedCol3 AND indexedCol4=:indexedCol4 LIMIT 1");
                $sql->execute($preparedValues);
                $return = $sql->fetchAll(PDO::FETCH_ASSOC);
}

On a dedicated server with 8GB RAM, the server uses >5% cpu/ram but takes a long time to finish the script.     Second Question What are some alternative designs?   Because the column values all happen to be alphanumeric, I could select the entire table and store it in an array. Accessing the keys like so: indexedCol1indexedCol2indexedCol3indexedCol4.   Results: MyISAM - Select Whole Table: 30 seconds MyISAM – Select Individual Rows (10k times) – 68 seconds InnoDB – Select Whole Table: 30 seconds InnoDB – Select Individual Rows (10k times) – 131 seconds     I am surprised it takes so long to select a whole table. The server resources use 1% for about 20 seconds, then cpu/ram jump to 30%+ for about 10 seconds. This is still drastically faster than individual selects.   In this instance, $bigList is over 500k items. At 68 seconds per 10k rows it’s absurdly long. Building an array with key/values is the only realistic way I currently know of, but I suspect there is a much better way of doing this.     As far as I know, I cannot do a select like so: SELECT * FROM t1 WHERE (column1,column2,column3) IN  ((val1, val2,val3), (val4, val5,val6)) There is no way to determine whether a row was found for each entry as far as I know. 

Hello folks, 

So, not sure where to start, but I'm wondering if it's at all possible to change a prepared statement / sql based on whether or not we're displaying for desktops, or for smartphone/tablets? I'm not sure what to start looking at since I'm pretty new in PHP and all... 

I've managed to figure out how to change CSS if I'm on phone 

@media only screen and (max-width: 767.98px){
  // PUT CSS FOR PHONES...
}

Any directions on how I would change my SQL, would be awesome! I'd like to narrow down the columns returned if I'm on phone, otherwise breaks my pages looks too much...

Much thanks in advance!

Pat
