I have a HTML thus like:
<table>
<tr>
<th>Name</th>
<th>Email</th>
<th>Age</th>
</tr>
<tr>
<td>Joe Bloggs</td>
<td>joe#bloggs.com</td>
<td>40</td>
</tr>
<tr>
<td>John Doe</td>
<td>john#doe.com</td>
<td>40</td>
</tr>
</table>
Is there a way using xPath to get the first 2 columns, i.e the Name and Email fields?
I can get the table data using $data = $xpath->query( '//table'); just unsure how to get only the first 2 columns.
Many thanks
Get the first two td's:
//table/tr/td[position() <= 2]

I only know the basics of scraping webpages using php simple html dom. The webpage has several tables on it, all with the same classes - so nothing unique to each table.
<table class="table">
<tr>
<td>item 1</td>
<td>item 2</td>
<td>item 3</td>
</tr>
</table>
<table class="table">
<tr>
<td>item 4</td>
<td>item 5</td>
<td>item 6</td>
</tr>
</table>
<table class="table">
<tr>
<td>item 7</td>
<td>item 8</td>
<td>item 9</td>
</tr>
</table>
The code I have is working, however it's returning data from ALL tables, and I only want data from the first table. I'm using the following to find the rows of data :
$d1s = $dom->find('table.table tr');
I'm assuming it's a simple error I've made. Can anyone help ?
How can i create database tables using controllers in laravel. Is there any way?
Actually I want to create a table using another table column values.
Eg:
I have two tables called table1 and table2.
<table>
<thead>
<td>id</td>
<td>name</td>
</thead>
<tr>
<td>1</td>
<td>raj</td>
</tr>
<tr>
<td>2</td>
<td>john</td>
</tr>
<tr>
<td>3</td>
<td>sam</td>
</tr>
</table>
and I want the names as field names in table2
<table>
<thead>
<td>raj</td>
<td>john</td>
<td>sam</td>
</thead>
</table>
And I want to create table2 using controller
Why do you want to do that!? I see no reasons!
Anyway you can use raw query in controller :
DB::raw(' CREATE TABLE . .. ');
I retrieve data from DB and I need to insert all of them in a table.
I have some constant headers and some that depends on the query results.
Below you can see a table; how i want it to look like:
I did prepare the HTML structure:
<table class="table-fill">
<thead>
<tr>
<th>ID</th>
<th>CODE</th>
<th colspan=2>TREND A</th>
<th colspan=2>TREND B</th>
<th colspan=2>TREND C</th>
</tr>
<tr>
<th></th>
<th></th>
<th>Items</th>
<th>Revenue</th>
<th>Items</th>
<th>Revenue</th>
<th>Items</th>
<th>Revenue</th>
</tr>
</thead>
<tbody class="table-hover">
<tr>
<td>1</td>
<td>A</td>
<td>10</td>
<tD>150</td>
<td>5</td>
<tD>200</td>
<td>8</td>
<tD>120</td>
</tr>
</tbody>
No problem so far. The hard part is to use actual data from DB and insert them to the table.
Headers "trend a", "trend b" etc are not constants. The below tables will be displayed on different countries. Some countries have specific trend names. Let's say England has "Trend A", "Trend B" and "Trend D". Italy has only "Trend A" etc.
Is it possible to write php code and in some way auto generate the table headers based on the query results?
And then split the results by trend so that correct values will go to correct trend?
I know how to do a simple table like:
$sql_r = "SELECT o.id, o.code, tl.name, ts.items, ts.revenue
FROM overview o, trend_stats ts, trend_lang tl
WHERE o.id_shop = '1'
AND o.id = ts.id
AND ts.id_trend = tl.id_trend";
$data_to_output = Db::getInstance()->ExecuteS($sql_r);
foreach ($data_to_output as $data) {
echo '
<tr>
<td>'.$data['id'].'</td>
<td>'.$data['code'].'</td>
<td>'.$data['trend'].'</td>
<td>'.$data['items'].'</td>
<td>'.$data['revenue'].'</td>
</tr>
';
}
But I'm not sure how to split and structure them the way I want them to be. If there's any tutorial or anything online related to what I'm asking I'm happy to check it out. Thank you
I don't think you can do that other than rewrite your headers. The fact that you want to retrieve your informations from your database tells that you'll have to work with any kind of loop. So you first have to display your headers and then display your informations. The only way is to store somewhere in your loop the value that will change your headers when it changes, and add another line of header when the value actually changes. You can do that with just a simple if condition.
I have a requirement to output a table using Smarty and then have the user select a row to take them to another page.
I can display the table fine:
{html_table cols="Job Title,Salary,Sector,Location" loop=$results}
which gives:
<table border="1">
<thead>
<tr>
<th>Job Title</th>
<th>Salary</th>
<th>Sector</th>
<th>Location</th>
</tr>
</thead>
<tbody>
<tr>
<td>Dog walker</td>
<td>20000</td>
<td>None</td>
<td>London</td>
</tr>
<tr>
<td>F1 Driver</td>
<td>10000000</td>
<td>Financial Services</td>
<td>Scotland</td>
</tr>
</tbody>
</table>
but I am not sure if it is possible to add a hyperlink as an additional column to the table that links to a page using a hidden id.
So I would want something link this:
<table border="1">
<thead>
<tr>
<th>Job Title</th>
<th>Salary</th>
<th>Sector</th>
<th>Location</th>
<th>Apply</th>
</tr>
</thead>
<tbody>
<tr>
<td>Dog walker</td>
<td>20000</td>
<td>None</td>
<td>London</td>
<td>Apply</td>
</tr>
<tr>
<td>F1 Driver</td>
<td>10000000</td>
<td>Financial Services</td>
<td>Scotland</td>
<td>Apply</td>
</tr>
</tbody>
</table>
Is that possible?
Yes, but you need to modify the $results array before you pass it to Smarty so that the 4th element of each row contains the link as a string. There's no way to have {html_table} generate the link for you.
I have a table with a first column called: "Fruit", and a last column called: "Total"
And any columns in between are dynamically created by the number of students.
Below is what I'm looking to dynamically make, from what the database shows so far.
<table border="1">
<tr>
<th>Fruit</th>
<th>Sally</th>
<th>John</th>
<th>Total</th>
</tr>
<tr>
<td>apples</td>
<td>5</td>
<td>3</td>
<td>8</td>
</tr>
<tr>
<td>bananas</td>
<td>3</td>
<td>5</td>
<td>8</td>
</tr>
<tr>
<td>Oranges</td>
<td>3</td>
<td>3</td>
<td>6</td>
</tr>
<tr>
<td></td>
<td>11</td>
<td>11</td>
<td>22</td>
</tr>
</table>
Here's the difficulties I run into. The fruit names, students, and fruit consumed are pulled from the database.
And I don't know how many fruit rows nor student columns there will be.
This is as far as I got:
<table>
<tr>
<th>Fruit</th>
<?php $sqlS = db("SELECT s.*, sf.consumed FROM `tbl_students` s, `tbl_students_fruit` sf WHERE s.studentid = f.studentid ORDER BY s.studentname ASC");
while($student = mysql_fetch_array($sqlS)){ ?>
<th><?php echo $student['studentname'];?></th>
<?php } ?>
<th>Total</th>
</tr>
<?php $sqlF = db("SELECT * FROM `tbl_fruit` ORDER BY fruitname ASC");
while($fruit = mysql_fetch_array($sqlF)){ ?>
<tr>
<td><?php echo $fruit['fruitname'];?></th>
<td></td>
<td></td>
</tr>
<? } ?>
</table>
As you can see, I'm creating the Fruit rows, and Student columns. But it's incomplete. I've only created the column headers, and not the columns below the headers. From this point I am stuck on the guts of the table.
I am sure arrays are the way to go with this monstrosity. But the only way my feeble brain can make this work is to have more queries, which I'm sure is a very wrong way to do this.
If there were 3 students or 15 students, I can make them appear in the table th columns, but not in rows in their columns.
How does one traverse dynamic columns this way?
And if my demo above is confusing, I don't blame you!
well, I am assuming that your db structure is as follows:
[tbl_students]
studentid, studentname
[tbl_fruit]
fruitid, fruitname
[tbl_students_fruit]
id, fruitid, studentid, consumed

I haven't tested it, so good luck
